Push your limits with the 12kg Heavy-Duty Slam Ball, the ultimate tool for explosive power, metabolic conditioning, and functional strength. Often called a "dead ball" because of its no-bounce design, this 12kg weight is the perfect "sweet spot" load—heavy enough to build lean muscle, yet manageable enough for high-speed HIIT cardio and CrossFit WODs.
Engineered for commercial gyms, PT studios, and home garage gyms across Australia, this slam ball features a thick, tyre-tread grip shell filled with shifting iron sand. It is built to withstand thousands of maximum-effort slams against rubber gym tiles, concrete, or grass.

12kg Versatility: The ideal weight for bridging the gap between cardio speed and strength building. Perfect for thrusters, burpee slams, and rotational throws.

Floor Safe: The rubberised shell protects your gym flooring from scuffs and damage during drops.

Why Train with a 12kg Dead Ball?
-
Explosive Power: Unlike static weightlifting, slamming a ball forces your body to generate maximum force in minimum time, developing athletic power.
-
Core Stability: The shifting sand inside the ball forces your stabiliser muscles and core to work overtime to control the weight.
-
Total Body Conditioning: A simple "overhead slam" engages your lats, abs, triceps, glutes, and quads in a single movement.
-
Fat Loss: High-rep slam ball workouts keep your heart rate high, burning more calories than traditional isolation exercises.

Frequently Asked Questions
What is the difference between a Slam Ball and a Medicine Ball?
The main difference is the bounce. A Medicine Ball is typically leather or rubber and bounces back, making it good for wall throws. A Slam Ball (Dead Ball) like this 12kg version is filled with sand and designed not to bounce. This allows you to slam it into the floor with full force safely.
Can I use this 12kg ball for wall balls?
No. Because it is a "dead" weight with a hard rubber shell, throwing it at a wall may damage the plaster or the ball itself. For wall exercises, check our Soft Wall Ball range.
Is 12kg heavy enough for muscle building?
Yes. While 12kg might seem light for a deadlift, it is heavy for explosive movements. Performing 50 overhead slams or rotational throws with 12kg creates significant metabolic stress, which drives muscle endurance and hypertrophy.
What exercises can I do with a 12kg Slam Ball?
The 12kg ball is incredibly versatile. Popular exercises include: Overhead Slams (Total body power), Russian Twists (Core/Obliques), Bear Hug Squats (Legs/Glutes), Burpee Slams (Cardio), and Lunges with Rotation (Stability).
What surfaces can I slam on?
We recommend slamming on rubber gym tiles, stall mats, grass, or carpet. Avoid slamming directly on sharp gravel, asphalt, or rough concrete, as this acts like sandpaper and will shorten the life of the rubber shell.
Is this ball suitable for beginners?
12kg is a moderate weight. For absolute beginners or those recovering from injury, we recommend starting with 6kg or 9kg. However, for active individuals with some gym experience, 12kg is an excellent starting point for power training.
