12KG Slam Ball

GravoMax Slam Ball – 12KG

Overview

The GravoMax Slam Ball 12KG is built for athletes who want more than basic conditioning and need a stronger slam ball for serious training output. It adds meaningful resistance for explosive movement while still allowing controlled reps, making it a strong choice for strength-endurance work and full-body conditioning. This weight is well suited to functional training, CrossFit-style workouts, and HYROX-focused sessions where power, timing, and grip control need to stay consistent under fatigue.

Why choose the 12KG slam ball

The 12KG weight sits in a strong range for strength conditioning and explosive training. It is heavy enough to challenge output and muscular endurance, but still manageable for repeated slams, rotational work, and mixed conditioning drills when technique matters.

It is also a practical upgrade for athletes progressing from 10KG, because it increases resistance without forcing a complete change in training style. That makes it useful for structured progression in home gyms, PT studios, and commercial gym programming.

• 12KG resistance for stronger power output and conditioning
• Suitable for repeated slams with controlled movement
• Good for progression from mid-weight slam balls

Grip and construction

The ball uses a dense rubber shell filled with sand for a non-bounce slam ball feel. This helps absorb force on impact and keeps the ball grounded after each slam, which supports safer and more efficient conditioning sessions.

In addition, the tire-tread texture improves grip during overhead slams, rotational drills, and front-loaded movements. The heavy-duty outer construction is built to handle repeated impact in high-use training environments.

Best for

• Strength-conditioning progression
• Explosive power and endurance circuits
• Repeated overhead slams and rotational drills
• Functional fitness and HYROX-style training
• PT studios and commercial gym conditioning zones
