FAQ About Our Slam Balls for Sale

What is the difference between slam balls and medicine balls?

Slam balls and medicine balls may look similar, but each have their place in the gym: 

• Sand-filled and built to absorb impact, slam balls don’t bounce when slammed on the floor or against a wall.

• Medicine balls have a slightly bouncier design and are precision-filled for better balance and grip.

Essential for a well-rounded gym setup, both complement each other to target different aspects of fitness and performance.

What weight slam ball should I choose?

Choosing the right slam ball weight comes down to your strength training goals and how you plan to use it in your workout. Lighter balls let you focus on speed, technique and higher reps, while heavier options boost performance and help you build strength and power.

Here’s a simple way to match weight to your needs:

• 2  kg – 10  kg (22 cm diameter): Perfect for beginners, warm‑ups, rehab moves and faster, flow‑based circuits.

• 12  kg – 30  kg (30 cm diameter): Ideal for standard strength and conditioning sessions, explosive throws and slams.

• 50 kg (37 cm diameter): Heavy-duty option for advanced athletes and serious strength days that demand maximum force and control.

Pro tip: Start with a weight that allows good form throughout your set, then gradually increase it to push your performance as your strength builds. Never use a weight you are uncomfortable with, as this can quickly lead to injury.

What exercises can you do with slam balls?

Slam balls offer beginners and athletes a versatile full-body workout that targets arms, shoulders, legs and core. 

With our slam balls, you can perform a range of exercises, including:

• Overhead throws and overhead slams to build explosive power.

• Sit-ups and Russian twists for core strength and rotational movements
