If you’re looking to become a more well-rounded athlete, this dynamic training tool can help to improve muscle density and supercharge your aerobic capacity
Functional training is a term that has risen into the limelight in recent years. It appears to be in opposition to more bodybuilding focused gym routines, instead aiming to optimise physical fitness, strength and speed.
While not as high-tech as other modern gym equipment, the slam ball is a formidable companion to anyone looking to built explosive strength and muscular endurance. It offers a full-body workout, with enough versatility to be used in HIIT training, endurance, sports-specific or rehabilitation.
We’ve listed our top picks of slam balls below, with a few tips on how to use them at the bottom, so be sure to scroll all the way down.

Mirafit is a strength and conditioning manufacturer based in Norwich, UK. The brand is well-established in the fitness industry for its heavy-duty weights and machines.

What to consider when buying a slam ball?
Weight
Slam balls come in various weights, ranging from light, around 0.5-3kg, to significantly heavier, at 20kg and upwards.
Choose a weight that challenges you without compromising your form. It’s a good idea to start with a lighter weight and gradually increase as your strength and technique improve.
Material
Rubber is a popular material choice for slam balls due to its durability and impact resistance. Rubber slam balls are designed to withstand high-impact exercises, such as slams and throws, without easily deforming or breaking.
Vinyl offers durability and can withstand repeated slams and throws. Polyurethane (PU) slam balls are known for their durability and resistance to deformation.
Rubber, vinyl and PU slam balls often have a slightly tacky or textured surface, improving grip during exercises.
Leather slam balls provide a more unique feel and grip. They tend to be less bouncy than other materials, making them suitable for controlled slams and exercises where you want to limit the ball’s rebound.
Filler
Sand is a traditional filling material for slam balls. This filling is affordable and provides stable weight distribution.
However, they might become uneven over time due to shifting inside the ball and they can be more prone to wear and tear, potentially leading to ruptures.
Gel-filled slam balls contain a viscous substance that offers a unique feel and impact absorption. Gel-filled balls tend to have a consistent weight distribution and can withstand slams and throws effectively while reducing the risk of ruptures.
Ultimately, your decision is down to your training requirements and preferences.
