4KG Slam Ball

GravoMax Slam Ball – 4KG

Overview

The GravoMax Slam Ball 4KG is a versatile entry-level option for explosive conditioning, beginner strength work, and higher-rep training sessions. It gives slightly more resistance than the 3KG version while still allowing good movement speed and control, making it a strong choice for athletes building technique and consistency. This slam ball is suited to functional training, CrossFit-style workouts, and HYROX-focused conditioning where repeatable slams, clean transitions, and stable handling are important.

Why choose the 4KG slam ball

The 4KG weight is ideal for users who want more challenge than a light warm-up ball but still need a manageable load for controlled reps. Therefore, it works well for technique progression, conditioning circuits, and mixed training blocks where speed and posture need to stay consistent.

It is also a practical option in shared training spaces, because coaches can use it for movement prep, timed intervals, and beginner-to-intermediate slam ball progressions without jumping too quickly into heavier weights.

• Balanced 4KG resistance for progression and control
• Great for beginner to intermediate users
• Suitable for circuits and repeated slams

Grip and construction

The ball uses a durable rubber shell filled with sand for a non-bounce slam ball feel. This helps control rebound after impact and makes it easier to reset quickly between reps during conditioning sessions.

In addition, the tire-tread texture improves grip during overhead slams, front-loaded drills, and rotational movements, helping users maintain control during fast-paced training.

Best for

• Beginner to intermediate slam ball training
• Conditioning circuits and interval sessions
• Technique progression with controlled resistance
• Functional fitness and HYROX-style training
• PT studios and commercial gym conditioning zones
