Choosing the Right Slam Ball for You

A medicine ball is a popular training tool, and has been since the Ancient Persians used to stuff animal bladders with sand and toss them around. These days, medicine balls – and their popular cousin, slam balls – are a lot more refined and a lot less disgusting!

Not to be confused with inflatable exercise balls (i.e. Swiss balls), medicine and slam balls can be found in any good gym or CrossFit box, and are excellent tools for developing balance, coordination, power, explosiveness and core strength.

However, in addition to commercial use, slam balls and medicine balls are just as popular with home users looking to add another tool to their fitness arsenal, alongside dumbbells, kettlebells and good battle ropes.

If this is you and you are looking to buy a new weighted ball, make sure to read the following sections, which will guide you through the things to look out for before parting with your cash.


When it comes to design, you can split these weighted fitness balls into two categories – medicine balls (which bounce) and slam balls (which do not bounce). More on this below. You will also come across wall balls, which are not covered in depth in this article.

It is important to choose the correct ball, because buying the wrong kind of ball can be counterproductive at best, dangerous at worst. Ultimately, you can slam a no-bounce slam ball as hard as you like to the ground, effectively working your entire upper body. However, do the same with a bouncy medicine ball, and you risk a broken nose as the ball potentially bounces back up into your face!

Traditionally, a medicine or slam ball is roughly the size of a soccer ball or basketball, and will come in a multitude of weights. You will find that some brands offer consistent sizes regardless of the weight, while others produce smaller balls for lighter weights and larger sizes for heavier weights.

As for shape, while slam balls are pretty much always round, it is common to find medicine balls with slightly different profiles. For example, some will offer a pair of integrated handles or fabric handles attached to the surface.

These handles may not interest you if throwing and catching the ball is your main movement. However, for exercises where you hold the ball for sustained periods – such as performing Russian Twists, toe touches, crunches, or other core exercises – handles allow you to get a much better grip on the ball, as well as hold the ball in different ways.

Some medicine balls may go as far as adding an external handle to the exterior of the ball, blurring the line between medicine ball and kettlebell (…kettleball?). However, the actual usefulness of such an item is still up for debate.

Finally, let’s talk aesthetics. This is another point that may not interest you, considering the performance should always be paramount.

However, both slam balls and medicine balls come in different designs, whether no-nonsense and all-black, or retro and eye-catching. Some balls also come in different colors besides black, which is useful if you have a home gym and want your equipment to match (hey, we’re not judging!).

On the topic of colors, many manufacturers will color code their balls to represent different weights (i.e. 5lb is red, 10lb is blue, 20lb is yellow, and so on). This is particularly useful if you are buying multiple balls for your home gym.


The material the ball is made of will largely determine how it performs, although – as mentioned – the ball will have a specific purpose: to bounce or not to bounce.

A no-bounce slam ball is almost exclusively made with a thick rubber shell that stands up to constant high force as it impacts the ground.

Medicine balls also commonly feature a rubber skin, although you can also find them made from leather, synthetic leather, nylon, vinyl and even plastic.

For both medicine and slam balls, rubber skins will often be textured to increase grip. This may be as simple as dots (akin to a basketball) or as prominent as raised multidirectional tread, which enhances grip incredibly.

Most good slam balls will have ample grip for the majority of people, although if you need a boost, you can look into buying a pair of CrossFit gloves or even good CrossFit grips.


Both slam balls and medicine balls come in a wide range of weights to cater for a wide range of movements and users.

The exact weight selection will depend on the manufacturer of the ball. Some balls may just come in three or four weights, while others may come in 12 or more weight choices.

The actual weights offered will differ depending on the manufacturer, although typically you will find both styles of ball in weights ranging from a beginner-friendly 4lb right up a mammoth 100lb (usually a slam ball)!

What weight you choose is up to you, although don’t dive straight in and grab the heaviest ball you can find, as it will probably be counterproductive and could result in injury.

In short, you will want a weight that will slow your movement, but not at the cost of good form. For more on selecting the right weight for you, check out the FAQ section below.

Weight is added to these balls in multiple ways. In a slam ball, the manufacturer will usually stuff the ball with sand or iron filings, which both increases the weight and helps the ball absorb force, so it doesn’t bounce or roll when slammed to the ground.

Medicine balls, on the other hand, are often simply inflated with air, which helps the ball retain its round shape and improves the springiness for moves that require bouncing.

Frequently Asked Questions

We have touched upon this earlier in our buyer’s guide, although let’s clarify the difference between medicine balls and slam balls.

Firstly, both styles of ball have similarities. Of course, they are both weighted balls that are typically the size of a soccer ball, although some will be smaller and some larger.

Both styles of balls can be used for static holding during exercises such as squats, lunges, overhead presses and core work (such as crunches and rotational passes to a workout partner).

However, there are differences. The main one being that medicine balls are designed to bounce while slam balls are designed to stop dead as soon as they hit the ground.

Slam balls are also built with thicker rubber and are incredibly durable. They are therefore naturally well-suited for ball slams (where you lift the ball above your head, slam it into the ground, before picking the ball up and repeating).

Medicine balls are perhaps more versatile than slam balls, although they are are not designed to be thrown against a hard surface. As they are usually filled with air and generally springier in nature, they are prone to bouncing off in different directions, which is obviously dangerous.

In an ideal world, you would buy both a slam ball and a medicine ball, although if you can only afford one, try to determine what you want to achieve with your ball.

If you are buying a ball to throw explosively – whether at the ground or to a partner – a slam ball will be your best option. If you are looking for a ball for weightlifting, core exercises, passing to a partner (for rotational twists) or to use for press-ups, a medicine ball will be the smarter choice.

If you have used a slam ball in CrossFit or at the gym and are sold on buying one for your home workouts, then that’s great – but how do you pick the right one for you?

Firstly, you should determine the weight you require. You don’t want to be slamming something too light that feels like a soccer ball for 100 reps – that’s a waste of time. On the flip side, going in and buying a 90lb slam ball will be pointless if you can’t even lift it off the ground!

There are no written rules about what weight you should pick. It is recommended that you should aim for a ball that is heavy enough to slow your movement, but not so heavy that it causes you to break good form.

With medicine balls, it is often suggested that you use a ball of around 30% to 50% of your one-rep max (1RM) on a similar exercise. By this we mean that if your one-rep max on a barbell overhead press is 40lb, an appropriate medicine or slam ball for you would be around 15lb to 20lbs. Don’t know your 1RM? Check out our free one-rep max calculator!

This very general advice works if you are buying a ball mainly to use for squats, lunges and other exercises with which you could use a dumbbell. However, if you are looking to slam the ball, then this advice may not be suitable as there is no corresponding dumbbell/barbell exercise.

In this case, use a weight that you can perform around 8 to 12 reps with, but no more. Ultimately, you would want to be struggling to complete the 12th rep with good form. If this is the case, this is the right weight for you.

We know that a slam ball is designed to be slammed into the ground at high velocity. But what about a medicine ball?

While medicine balls may be poor for slamming due to their tendency to bounce, they are great for many other things in the fitness world. There’s a reason this simple weighted ball has been a gym staple for centuries!

Firstly, you can use it to replicate movements you would usually do with dumbbells and barbells (and even kettlebells, if your medicine ball has handles). This may include squats, lunges, overhead presses and front raises to name a few.

Using a ball allows you to take advantage of different grips and stimulate your muscles in different ways – providing the ball is heavy enough to be a challenge.

Unlike a dumbbell, a medicine ball is also capable of safely being tossed, thrown and caught – for example, to a workout partner or against a wall. This can help you develop explosive power, which is key for sportspeople and athletes.

Medicine balls are also traditionally used for core movements – for example, using them for exercises such as crunches, woodchoppers, toe touches, and Russian Twists (all easier with balls that have integrated handles by the way).

You can also use the ball to add instability to movements such as planks, press ups, reverse planks, and mountain climbers.

Providing you can use your imagination – or follow hundreds of online medicine ball workouts – then you will never find yourself out of uses for your new medicine ball!

A ball slam is a key movement in CrossFit, helping you build strength and power in your upper body and core, while also being a pretty good cardio exercise too. So how do you do one?

Place your feet shoulder-width apart with the slam ball (don’t use a bouncy medicine ball) on the floor in front of you. Then squat down with a straight back, pick up the ball and stand up. As you stand, lift the ball above your head so that your arms are fully extended. At this point, engage your core and slam the ball down onto the floor as forcefully as you can. This is one rep.

To add slams to your existing workout, you should aim to perform around three sets of 8 to 15 reps. For CrossFit, simply follow the reps prescribed in your WOD.

As you become stronger, you should increase the reps per set as well as the weight of the ball you use. You can also add in variations, such as burpee ball slams – an exhausting move incorporating a burpee in between each slam of the ball.

Be sure to warm up thoroughly before starting a ball slam session. Also, ensure you are wearing a pair of closed-toe shoes for some foot protection – a good pair of CrossFit shoes will usually do the job.
