25KG Slam Ball

GravoMax Slam Ball – 25KG

Overview

The GravoMax Slam Ball 25KG is a heavy-duty slam ball built for advanced athletes who need serious resistance for explosive conditioning and strength-endurance training. At this weight, every rep requires strong bracing, full-body coordination, and controlled power output. It is a practical choice for functional training, CrossFit-style sessions, and HYROX-focused conditioning where you want heavier loading without relying only on rigid free weights.

Why choose the 25KG slam ball

The 25KG weight is designed for advanced strength conditioning and high-resistance power work. It creates a much higher training demand than mid-range weights, making it ideal for athletes who want stronger force production and better power-endurance under fatigue.

It is also a strong choice for commercial gyms and PT spaces that need a heavier slam ball option for advanced users, because it supports explosive training while still offering the safety and control of a non-bounce design.

• 25KG resistance for advanced power and conditioning
• Suitable for heavy training blocks and strength-endurance work
• Built for serious athletes and high-output sessions

Grip and construction

The ball uses a durable rubber shell filled with sand for a non-bounce slam ball feel. This helps absorb impact and keeps the ball grounded after each slam, which is especially important during heavy reps and high-intensity conditioning work.

In addition, the tire-tread texture improves grip during overhead slams, front-loaded movements, and carries. The heavy-duty outer construction is made to handle repeated impact in demanding home gyms, PT studios, and commercial facilities.

Best for

• Advanced strength-conditioning progression
• Heavy explosive slam ball training
• Power-endurance circuits and loaded conditioning
• Functional fitness and HYROX-style training
• Commercial gym conditioning zones and PT studios
