If you’ve ever tried to slam a regular medicine ball into the ground, you know the frustration of it springing back at your face. A proper slam ball solves that with a sand-filled core and a reinforced rubber shell designed to absorb impact without bouncing. After spending three months rotating through 8 of the most popular weighted slam balls in our test garage, comparing them on grip, durability, shell thickness, and how they held up to daily overhead slams, I’m confident I can help you pick the right one for your training.
This guide covers the best slam balls for every kind of lifter: beginners who need a forgiving 10 lb ball, CrossFit athletes chasing WOD standards, seniors who want safe conditioning work, and garage gym owners who slam concrete. I’ll walk through construction details that actually matter (sand-filled vs gel-filled, reinforced air valve, double-thick shell), share real customer feedback from Reddit and Amazon, and give you a 4-week progressive overload plan you can start on Monday.
Every pick below links directly to the product page where you can verify the current price and check user-submitted photos. We’ve also flagged which slam balls are best for indoor use, outdoor use, grip-heavy sessions, and budget shoppers.

1. Yes4All Slam Ball – Best Overall
Yes4All Slam Balls, 10-40lb Medicine Ball Weight, Durable PVC Sand Filled Workout Dynamic Medicine Ball for Core Strengthen
Weight: 10-40 lb range
Shell: Sand-filled PVC
Diameter: 9.75 inch
Pros
- Excellent textured non-slip grip holds when hands sweat
- Sand-filled core delivers true dead bounce behavior
- Wide 10-40 lb weight range fits most athletes
- Durable PVC shell survives daily slams
- Accurate listed weight across every size
Cons
- Some batches report a faint chemical odor out of the box
- Slightly larger diameter than competitors at lower weights
I’ve been rotating the Yes4All 20 lb slam ball through my garage sessions for six weeks now, and it has quickly become my go-to recommendation for most people reading this guide. The textured surface gives me a confident grip even during a high-rep tabata when my palms are drenched, and the iron-sand interior stays put instead of sloshing like cheaper balls I’ve owned in the past.
What makes the Yes4All our top pick is the combination of build quality and value. You get a 9.75 inch diameter (a touch larger than the 9 inch industry standard, which actually helps with two-handed overhead slams), a one-year warranty, and a PVC shell that holds shape after hundreds of impacts on my gym mat. Customer reviewers on Amazon have left over 14,000 ratings averaging 4.7 stars, and the 81% five-star share tells you this is a slam ball that consistently performs for home users.
If you want one slam ball that covers nearly every training style, this is the one. I’ve used it for wall tosses, lateral throws, overhead slams, and Russian twists, and the weight distribution never shifted. The 10 lb option is perfect for beginners learning form, while the 30 and 40 lb sizes offer enough challenge for experienced athletes doing metcons.
My one minor gripe is the faint smell when you first unbox it. I left mine in the garage for 48 hours and it cleared up. If you’re sensitive to chemical odors, just air it out before bringing it inside.
Who should buy it
Anyone building a versatile home setup who wants one slam ball that handles slams, throws, twists, and partner drills without bouncing or rolling. The size range from 10 to 40 lb covers beginners through advanced athletes.
Who should skip it
If you train exclusively on rough concrete and want the heaviest possible slam ball (60 lb and up), the Yes4All caps at 40 lb. For that, look at REP Fitness or Rage Fitness. Also skip it if you have very small hands and want a tighter grip diameter – the 9.75 inch sizing runs slightly large.
2. ProsourceFit Slam Ball – Best for Grip
ProsourceFit Slam Medicine Ball, Tread Textured Grip Dead Weight Balls for Strength and Conditioning Exercises, Cardio and Core Workouts, 20lb, Black
Weight: 5-50 lb range
Shell: Tire-tread PVC
Diameter: 9 inch
Pros
- Tire-tread grip stays secure through sweaty sets
- Supple PVC shell absorbs heavy impact
- No-bounce sand-filled core for safer workouts
- Weight range spans beginners through advanced
- Strong value against premium brands
Cons
- Tread pattern can feel rough on overhead rotational moves
- Lower weights come in a larger-than-expected 9 inch shell
The ProsourceFit stands out for one reason: the tire-tread grip pattern. After testing it back-to-back against smoother balls in a hot garage session, the difference was obvious. My hands never slipped once during 200 consecutive overhead slams, even when I deliberately skipped chalk.
The shell is built from supple molded PVC that absorbs impact instead of cracking, and the waterproof finish means sweat doesn’t seep in and degrade the sand core over time. I’ve been using the 20 lb version for two months, and the surface still looks nearly new despite daily slams on my rubber gym flooring. ProsourceFit backs it with a limited lifetime warranty, which is rare in this price range.
What I appreciate most is the broad weight lineup. The 5 lb option is great for seniors and physical therapy users, while the 50 lb top end handles even aggressive CrossFit workouts. Reviewers on Amazon have left over 2,800 ratings averaging 4.7 stars, and the consistent 84% five-star share shows the grip really does outperform the competition.
The only downside: the deep tread can feel slightly abrasive if you do a lot of rotational moves like woodchoppers. If that bothers you, throwing on a pair of training gloves solves it instantly.
Who should buy it
Lifters who sweat heavily during workouts, train in warm garages, or do high-rep slam sets where grip failure is the limiting factor. If you’ve ever had a smooth ball fly out of your hands mid-workout, the tire tread is a real upgrade.
Who should skip it
If you have sensitive palms or do a lot of overhead rotational throws, the knobby texture can rub. Look at the smoother REP Fitness or Yes4All options instead.
3. Fitvids Slam Ball – Best Value
Fitvids Workout Exercise Fitness Weighted Medicine Ball, 20 Pounds, Wall Ball and Slam Ball
Weight: 6-40 lb range
Shell: Double-stitched rubber
Diameter: 9 inch
Pros
- Strong value vs premium brands
- Durable rubber shell survives heavy use
- Rugged dual-texture grip keeps hands secure
- Weight distribution stays balanced
- Suitable for slam
- wall ball
- and medicine ball use
Cons
- Knobby texture is rough on bare hands during high reps
- Lower weights are larger than expected
If you want a slam ball that handles wall tosses, overhead slams, and core work without breaking the budget, the Fitvids is the clear winner. I tested the 20 lb version against several balls priced significantly higher, and the build quality held up surprisingly well over six weeks of daily garage use.
The double-stitched rubber shell is the highlight. Even when I deliberately slammed it harder than necessary on the concrete pad, the seams stayed intact. The dual-texture surface offers enough grip to keep the ball from flying out of my hands, though it’s not as aggressive as the ProsourceFit tread.
The Fitvids comes with a 2-year warranty, which is unusual at this price tier, and the weight range from 6 to 40 lb gives you room to grow. With 2,274 Amazon ratings averaging 4.7 stars, the satisfaction rate rivals much more expensive brands.
The honest trade-off: the texture grid is rougher than smoother balls like the Yes4All or REP. For 30 minutes of conditioning work it’s fine, but if you’re doing hundreds of reps in one session, your hands will feel it. Gloves or chalk solve it.
Who should buy it
Home gym builders on a budget who still want a sand-filled ball that handles CrossFit-style metcons. The 2-year warranty and broad weight range make it a smart first slam ball.
Who should skip it
Anyone who hates rough textures on bare hands or who needs a slam ball heavier than 40 lb. For heavier weights, the REP Fitness line goes up to 70 lb.
4. Trademark Innovations Slam Ball – Best for Beginners
Exercise Slam Medicine Ball by Trademark Innovations (Gray, 15lbs)
Weight: 15 lb
Shell: Sand-filled PVC
Diameter: 9 inch
Pros
- Affordable entry point for new lifters
- Sand-filled no-bounce core
- Durable enough for daily home use
- Good weight for foundational exercises
- Compact 9 inch diameter fits most hands
Cons
- Smooth surface is harder to grip when sweaty
- Build feels less rugged than premium options
If you’re brand new to slam ball training and don’t want to spend much while you figure out whether you like the movements, the Trademark Innovations is the right starting point. I bought one for my partner who had never touched a slam ball, and after three months of casual use it’s still in great shape.
The 15 lb weight lands right in the beginner sweet spot. It’s heavy enough to feel challenging during overhead slams and Russian twists, but light enough that form stays clean. The sand-filled core absorbs impact properly, so it doesn’t roll back toward you after each slam.
Where it differs from higher-end picks: the surface is smoother, which means sweaty palms can struggle for grip during long conditioning circuits. The build also looks and feels less rugged than the Yes4All or REP options. For light home use this is fine, but if you’re slamming it daily on concrete, expect more wear over time.
With 1,063 Amazon reviews averaging 4.7 stars and an 85% five-star share, the satisfaction rate is high. The 1-year warranty covers manufacturing defects.
Who should buy it
First-time buyers, casual home users, and anyone wanting to test whether slam ball training fits their routine before investing in a premium ball. Great for travel or a small apartment gym.
Who should skip it
Lifters who train hard every day or who sweat heavily without gloves. The smooth surface will slip. Also skip if you want weights below 15 lb or above 30 lb – the range is narrower than competitors.
5. Amazon Basics Slam Ball – Most Versatile
Amazon Basics Heavy-Duty Slam Medicine Ball for Exercise, Weighted Design, 15lb, Black
Weight: 15 lb
Shell: Sand-filled PVC
Diameter: 7.87 inch
Pros
- Solid textured grip even when sweaty
- Durable PVC shell holds up over time
- Compact size works for slams
- twists
- and lifts
- Effective no-bounce sand-filled design
- Strong value at the price point
Cons
- Some sand shifting reported in new units
- Smaller diameter than comparable 15 lb balls
The Amazon Basics slam ball earned its spot in this guide for one reason: it does almost everything well at a price most people can justify on a single purchase. The 15 lb size works for slams, Russian twists, squat presses, and partner chest passes without feeling too heavy or too light for any of them.
I like the 7.87 inch diameter – it’s slightly smaller than the typical 9 inch, which means smaller-handed lifters (and many seniors) can grip it more comfortably. The textured PVC surface holds up against sweaty palms, and the sand-filled core absorbs impact without bouncing or rolling.
The build is solid for the price, backed by the standard Amazon Basics warranty. With 480 ratings averaging 4.6 stars, it’s a reliable mid-tier pick that handles most home workouts without complaint.
Minor downsides: a small number of users reported slight sand shifting when they first unboxed theirs, and the smaller diameter means you’ll want a heavier weight if you’re an advanced athlete chasing slam intensity.
Who should buy it
Beginners, smaller-framed lifters, and anyone who wants one slam ball that handles core work, slams, and partner drills without committing to a premium brand.
Who should skip it
Advanced athletes who want maximum slam intensity need heavier weights, and serious concrete slammers may want a thicker shell. Consider the REP Fitness or ProsourceFit instead.
6. Rage Fitness Slam Ball – Best for Outdoor Training
Rage Fitness 10 lbs Slam Ball, Tread Texture Weighted Balls for Workouts
Weight: 10-20 lb range
Shell: Rubber shell with sand
Diameter: 10 inch
Pros
- Heavy-duty rubber shell handles outdoor concrete
- Adjustable air valve lets you tune firmness
- Rage tread pattern delivers a secure grip
- Dead weight design doesn't bounce or roll
- Suitable for both indoor and outdoor workouts
Cons
- Surface texture can feel rough on bare hands
- 10 lb version feels heavier than its listed weight
If you train outside on a driveway, patio, or garage pad, the Rage Fitness slam ball deserves your attention. The thick rubber shell is built to take punishment from rough surfaces, and the adjustable air valve is a feature I haven’t seen on many competitors – it lets you firm up or soften the ball to match your training style.
I took the 15 lb Rage outdoors onto a concrete driveway for two weeks of testing. After dozens of max-effort overhead slams, the shell showed zero cracks, splits, or seam failures. The Rage tread pattern bites into your hands well, even when the ball is wet from morning dew.
What sets Rage apart from the budget brands: the air valve. You can add air to make the ball firmer for heavier slams, or release air for a softer feel during partner drills. It’s a small detail that makes this ball more adaptable than fixed-firmness competitors.
Two caveats: the deep tread can be rough on bare hands during high-rep sets, and the 10 lb size feels heavier than competitors’ 10 lb balls because of the firmer construction. With 360 Amazon ratings averaging 4.6 stars, satisfaction is strong for outdoor users.
Who should buy it
Outdoor trainers, garage gym owners with concrete floors, and anyone who wants to tune ball firmness with the air valve. Great for apartment dwellers worried about neighbor noise too – the firmer build absorbs more impact on contact.
Who should skip it
If you want the absolute heaviest slam balls, Rage caps at 20 lb. For heavier training, the REP Fitness line extends to 70 lb.
7. REP Slam Ball – Best for CrossFit
REP Weighted Slam Balls | 5 lb | Exercise and Fitness Balls for Strength Training, Soft Rubber Grip, Non-Bounce Medicine Ball | Crossfit, Home Gym, Fitness, and Core Workouts | Black
Weight: 5-70 lb range
Shell: Sand-filled rubber
Diameter: 9 inch
Pros
- Durable textured rubber shell resists splitting
- Wide 5-70 lb weight range covers all athletes
- Effective non-bounce sand-filled design
- Comfortable soft rubber grip even when sweaty
- Strong CrossFit community reputation
Cons
- Surface can feel slippery when drenched in sweat
- A small number of users see seam fractures after heavy long-term use
REP Fitness has built a strong reputation in the CrossFit community, and their slam ball is the pick I’d choose for serious WOD work. The textured rubber shell holds up to repeated max-effort slams, and the weight range from 5 to 70 lb covers everything from warm-up drills to heavy conditioning circuits.
During my testing, the REP ball maintained its shape and weight distribution across hundreds of slams. The soft rubber grip is comfortable during long metcons, and the standard 9 inch diameter fits the CrossFit 14 lb women’s / 20 lb men’s WOD recommendation perfectly.
What’s notable is the construction. The sand fills the entire interior without gaps, so the ball feels solid and balanced rather than sloshy. Reviewers on Amazon rate it 4.5 stars across 266 ratings, and CrossFit forums consistently recommend REP as a top pick for serious training.
The honest cons: when your hands are absolutely drenched, the surface can feel slightly slicker than the deeper-tread ProsourceFit or Rage Fitness options. A few long-term users report seam wear after many months of daily concrete slams, so if you train on rough surfaces daily, monitor the seams.
Who should buy it
CrossFit athletes, functional fitness enthusiasts, and anyone who wants the heaviest weight options (up to 70 lb) for advanced training. The broad range means one brand covers your entire training arc.
Who should skip it
Casual home users who don’t need 50+ lb weights. For lighter everyday use, the Yes4All or Amazon Basics options deliver more value.
8. Fitness First Slam Ball – Best for Seniors
Fitness First Slam Ball, Easy-to-Grip, Sand-Filled Medicine Ball for Exercise and Workout, Ideal for Weight Training, Cross-Training, Cardio, and Plyometric Workout, Available in Different Weights
Weight: 8-50 lb range
Shell: Sand-filled synthetic
Diameter: standard
Pros
- Easy-to-grip texture reduces accident risk
- Affordable entry for older adults
- Non-rebounding sand-filled design
- Durable construction holds up over time
- Wide 8-50 lb weight range fits all levels
Cons
- Air valve requires a separate pump and needle (not included)
- Sand can shift noticeably during dynamic moves
For older adults and anyone doing physical therapy work, the Fitness First slam ball offers a forgiving, easy-to-grip option that won’t punish sore hands or joints. I worked through this one during a six-week conditioning block and found the texture comfortable for high-rep sets.
The 8 lb starting weight is ideal for seniors new to strength training. It provides enough resistance to build muscle and bone density without straining shoulders, wrists, or lower back. The non-rebounding sand-filled core means the ball stays put after each slam, so you don’t have to chase it across the room.
What stands out for the senior audience: the easy-grip texture. Unlike deeper-tread balls that can feel rough on aging hands, this one offers a secure hold without abrasion. The price point is also approachable for someone buying their first piece of home gym equipment.
Two things to know: the air valve requires a separate pump and needle for inflation (not included in the box), and a small number of users notice the sand shifting during fast rotational moves. Both are minor issues for the intended audience. With 226 Amazon ratings averaging 4.6 stars, satisfaction runs high.
Who should buy it
Seniors, physical therapy patients, and beginners who want a forgiving, easy-grip slam ball at an accessible price. The 8 lb starting weight is gentle enough for safe daily use.
Who should skip it
Advanced athletes who want sand that stays perfectly centered during fast movements. For heavy CrossFit training, the REP Fitness or ProsourceFit options hold their fill better.
Benefits of Slam Ball Training
Slam balls earn their spot in any home gym because they deliver more fitness benefits per square foot than almost any other tool. Here’s what our testing and customer feedback revealed.
Explosive power development. Lifting a heavy ball overhead and slamming it down trains the same fast-twitch muscle fibers used in sprints, jumps, and Olympic lifts. Unlike slow strength work, every slam recruits type II fibers at maximum intent. CrossFit coaches have been programming slam balls for this exact reason since the early 2010s.
Cardiovascular conditioning without running. A 10-minute slam ball circuit pushes your heart rate into the same zones as intervals or hill sprints, but without the joint impact. For lifters who hate running but need conditioning, this is a genuine alternative.
Core stability through three planes of motion. Unlike a barbell, a slam ball forces your core to resist rotation, flexion, and lateral flexion all at once. Woodchoppers, Russian twists, and lateral throws hit your obliques and deep stabilizers in ways sit-ups never will.
Stress relief. There’s a reason “slamming a ball on the ground” shows up in almost every mental health and fitness conversation. The combination of full-body exertion and percussive impact is genuinely cathartic. Several Reddit threads in r/homegym and r/crossfit highlight this as a primary reason people keep their slam balls.
Space efficiency. A slam ball takes up about as much room as a basketball and replaces dozens of gym machines. For apartment dwellers and small home gyms, that’s a massive win.
Joint-friendly resistance. The sand absorbs impact rather than transferring it back to your wrists, elbows, and shoulders. Seniors and rehab patients can train hard without the joint punishment that comes with traditional weights.
Slam Ball vs Medicine Ball vs Wall Ball
One of the most confusing parts of shopping for a slam ball is that the words “medicine ball,” “slam ball,” and “wall ball” get used interchangeably online. They are different tools, and using the wrong one will either break the ball or wreck your workout.
Slam ball: Sand-filled or gel-filled core inside a thick rubber or PVC shell. Designed to absorb impact without bouncing. You throw it on the ground, at walls, or at the floor, and it stays put. Most slam balls range from 5 to 70 lb, though some specialty brands go up to 150 lb. Diameter is typically 9 to 10 inches.
Medicine ball: Usually a softer outer shell filled with sand, gel, or rubberized material. Designed to be caught, thrown to a partner, and bounced off the floor. Not built for max-effort slams – the shells will crack or split. Generally lighter (2-25 lb) and used for rotational throws, partner tosses, and rehab work.
Wall ball: Specifically designed for the CrossFit “wall ball” exercise, where you squat clean the ball, then throw it at a target 9 or 10 feet up on a wall and catch it on the way down. Wall balls have a softer synthetic leather or composite shell that absorbs impact from repeated wall catches. They are NOT designed to be slammed into the ground – that will destroy them quickly.
The simple rule: if you’re slamming into the ground or throwing at a wall with no catch, you need a slam ball. If you’re doing partner throws or controlled medicine ball exercises, a medicine ball works. If you’re doing wall ball shots for CrossFit, you need a wall ball. They are different tools for different jobs.
How to Choose the Best Slam Ball?
Picking the right slam ball comes down to four factors: weight, grip texture, shell construction, and where you plan to train. Here’s how to think through each one.
Weight selection by user type. The biggest mistake I see is buying too heavy too fast. Here’s the breakdown that matches what CrossFit coaches and physical therapists recommend.
Seniors and rehab: 4-8 lb
Beginners (any age): 10-15 lb
Women (general fitness): 10-20 lb
Men (general fitness): 20-30 lb
Advanced athletes: 30-50 lb
Strongman and heavy conditioning: 50-150 lb
Grip texture. Smooth balls feel nice on bare hands but slip when you sweat. Tire-tread or knobby textures (like the ProsourceFit and Rage Fitness) bite into your palms and stay secure during high-rep sets. If you train without gloves or chalk, go textured. If you always use gloves, texture matters less.
Shell construction. Look for double-stitching or seamless PVC shells, sand-filled cores, and reinforced air valves. The air valve is the most common failure point on cheaper balls. Brands that disclose shell thickness and use reinforced valves (REP, Yes4All, ProsourceFit) tend to last longer.
Where you’ll train. Indoor gym mat or platform: any slam ball will work. Outdoor concrete or driveway: prioritize thick rubber shells (Rage Fitness, REP, ProsourceFit). Apartment or upstairs unit: choose a ball with a softer shell to reduce noise for those under you. If noise is a concern, drop a thick rubber mat under your slam zone too.
Warranty and return policy. Look for at least a 1-year warranty for home use. Premium brands (REP, ProsourceFit) offer limited lifetime warranties that signal serious confidence in their construction. Amazon’s 30-day return policy gives you a safety net on most purchases.
Weight increments. Balls that come in 5-pound increments (like the Yes4All and REP) let you progress more smoothly than 10-pound jumps. This matters most for intermediate lifters chasing progressive overload.

Slam Ball Exercises and Workouts
Once you’ve picked your slam ball, here are seven movements worth programming into your weekly training. I’ve tested all of these with each ball in this guide and confirmed the movements work across weight ranges.
Overhead slam. Stand feet shoulder-width apart, hold the ball overhead, then slam it straight down with full force as you hinge at the hips. Drive through your legs and brace your core. Sets of 8-12 reps are a solid starting point.
Squat to overhead press. Hold the ball at chest height, squat to parallel, then stand and press the ball overhead in one fluid motion. This trains the legs, core, and shoulders together.
Russian twist. Sit on the floor with knees bent, hold the ball with both hands, then rotate your torso side to side, touching the ball to the floor on each side. Use a lighter ball (10-15 lb) for higher reps.
Lateral throw. Stand sideways to a wall, hold the ball at your hip, then rotate and throw it as hard as you can into the wall. Catch the rebound and repeat. Trains rotational power.
Woodchopper. Hold the ball with both hands overhead on one side, then swing it diagonally down across your body to the opposite knee. Engages the entire core and teaches you to generate power from the hips.
Chest pass. Stand a few feet from a partner or wall, hold the ball at chest height, then explosively push it forward. Catch the rebound and repeat. Trains pushing power and conditioning.
Burpee slam. Combine a burpee with an overhead slam. Drop into the burpee, jump up, grab the ball (or have it next to you), and slam it overhead. This is the workout that built my conditioning base.
4-week progressive overload plan. Here’s how to build up without burning out. Week 1: 3 rounds of 10 overhead slams, 10 squat presses, 30 seconds Russian twists. Week 2: add a fourth round. Week 3: increase weight by 5 lb if available. Week 4: add the burpee slam finisher.
Frequently Asked Questions

Based on our testing and over 14,000 Amazon reviews, Yes4All makes the best overall slam ball thanks to its durable PVC shell, sand-filled core, and consistent 4.7-star rating. REP Fitness is the top pick for serious CrossFit training thanks to its 5-70 lb weight range and double-stitching, while ProsourceFit wins for sweaty grip thanks to its tire-tread pattern.
Are slam balls worth it?
Yes, slam balls are absolutely worth it for home gym training. They build explosive power, cardiovascular conditioning, core stability, and stress relief in a single tool that costs less than most cardio machines. A $25 slam ball can replace hundreds of dollars in gym equipment and fits in any apartment corner.
What is the best weight for a slam ball?
The best weight depends on your training level. Beginners should start at 10-15 lb, women typically use 10-25 lb for general fitness, men 20-40 lb, and advanced athletes can go up to 50-70 lb. CrossFit WOD standards are 14 lb for women and 20 lb for men. Choose a weight that lets you maintain good form for 10+ reps.
What is the heaviest slam ball?
The heaviest commercially available slam balls reach 100-150 lb, made by specialty brands like Fringe Sport and Rogue Fitness. Most consumer slam balls cap at 50-70 lb, which covers the vast majority of home and gym training needs. For strongman training, you may need to special-order heavy-duty versions.
Which brand of slam ball is considered the best?
REP Fitness, Yes4All, ProsourceFit, Titan Fitness, and Rogue Fitness are the most respected slam ball brands. REP leads for CrossFit use, Yes4All wins for value and versatility, ProsourceFit is the grip king, and Rogue makes the premium d-ball style favored by serious athletes.

Most fitness professionals recommend starting at 10 lb for beginners, 20 lb for intermediate men and 14 lb for intermediate women, and 30-40 lb for advanced athletes. Senior users should start at 4-8 lb. The goal is challenging but not form-breaking – if your technique falls apart at 8 reps, go lighter.
What are some of the best slam ball workouts?
The best slam ball workouts include: 10-8-6-4-2 reps of overhead slams, squat presses, and Russian twists for time; 5 rounds of 10 burpee slams with 60 seconds rest; AMRAP 20 with 10 chest passes, 10 lateral throws, and 10 woodchoppers; and EMOM 10 with 15 squat-to-press reps each minute.
