20KG Slam Ball

GravoMax Slam Ball – 20KG

Overview

The GravoMax Slam Ball 20KG is built for athletes who want heavy slam ball training with serious resistance and full-body demand. At this weight, every rep challenges strength, coordination, and endurance at the same time, making it a strong option for explosive conditioning and advanced training blocks. It is well suited to functional training, CrossFit-style workouts, and HYROX-focused sessions where power output, grip security, and movement control must stay consistent under fatigue.

Why choose the 20KG slam ball

The 20KG weight is a high-resistance option for strength conditioning and advanced power development. It is ideal for athletes who want heavier overhead slams, loaded conditioning work, and stronger core engagement without moving to rigid free-weight-only training.

It is also a practical choice for coaches and serious training spaces that need a heavy slam ball for progression, because it adds a demanding load while still supporting explosive movement and repeatable reps.

• 20KG resistance for advanced power and conditioning work
• Suitable for heavy slam intervals and strength-endurance sets
• Built for serious progression in functional training

Grip and construction

The ball uses a durable 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 training and cleaner transitions during heavy conditioning work.

In addition, the tire-tread texture improves grip during overhead slams, rotational drills, and loaded carries. The heavy-duty outer construction is designed to handle repeated high-impact use in demanding home and commercial gym environments.

Best for

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