40KG Slam Ball

GravoMax Slam Ball – 40KG

Overview

The GravoMax Slam Ball 40KG is an ultra-heavy slam ball built for advanced athletes who want maximum resistance for explosive conditioning and strength-endurance work. At this weight, every rep becomes a full-body effort that demands bracing, grip control, and precise movement under load. It is a serious training tool for functional fitness, CrossFit-style workouts, and HYROX-focused conditioning where heavy power output and controlled repetitions matter.

Why choose the 40KG slam ball

The 40KG weight is designed for maximum strength conditioning and high-resistance power training. It is ideal for experienced users who need a heavier slam ball for advanced progression, loaded conditioning circuits, and serious strength-endurance development.

This weight works especially well in commercial gyms and PT environments that train strong athletes, because it delivers a heavy stimulus while still keeping the control and safety benefits of a non-bounce design.

• 40KG resistance for maximum-load conditioning work
• Suitable for advanced athletes and serious progression
• Built for explosive power and strength-endurance training

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 critical when training at heavier loads and high intensity.

In addition, the tire-tread texture improves grip during overhead slams, carries, and rotational movements. The heavy-duty outer construction is designed to handle repeated high-impact use in advanced home gyms, PT studios, and commercial training spaces.

Best for

• Maximum-load strength-conditioning progression
• Heavy explosive slam ball training
• Power-endurance circuits and loaded conditioning
• Functional fitness and HYROX-style training
