Medicine Ball PEZZI Original Heavyball – weighted fitness ball for strength and core training

PEZZI Original Heavyball is a soft, weighted medicine ball designed for strength, power and core conditioning. Made from a durable, non-slip material, the ball can be filled with water or sand to change its weight between about 0.9 and 3.0 kg. Unlike rigid dumbbells, this soft Heavyball reduces the risk of injury when used in dynamic exercises such as throws, slams and partner drills, and can be used with hands or feet for a variety of functional and rehabilitative movements.

Advantages

The soft construction and non-slip surface give a secure grip during dynamic movements while the ability to adjust fill weight provides flexibility for progression and varied training goals. The durable material withstands repeated impacts and the ball’s design supports throwing, slamming, rotational and partner exercises that develop core stability, coordination and overall functional strength.

Suitable for

• Gym strength and power training (throws, slams)
• Core conditioning and rotational work
• Rehabilitation and controlled functional movements
• Home workouts and partner drills
• Agility and endurance circuits

When it may not be suitable

The PEZZI Heavyball is not ideal for traditional barbell-style resistance training or exercises that require a perfectly rigid implement. Users who need precise calibrated weights for competition or who prefer solid, heavy metal training tools may find soft medicine balls less suitable.

Key specifications

• Construction: soft, impact-absorbing material with non-slip surface
• Adjustable weight range: approximately 0.9–3.0 kg (fillable with water or sand)
• Intended use: throwing, slamming, partner drills, rotational and core exercises
• Suitable for use with hands or feet
• Durability: designed for repeated impact in fitness settings

How to use

Fill the ball to the desired weight using water or sand according to your training goals and ensure the filler is securely closed before use. Use the ball for dynamic movements such as overhead throws, slams, rotational tosses and partner passes, or incorporate it into core circuits and rehabilitation protocols. Start with lighter weights to learn correct technique, then increase fill gradually as strength and control improve.

What to consider before purchase

• Planned exercises: choose a ball weight that suits throwing, slamming or core work
• Space and surface: ensure adequate workout space and impact-safe flooring for slams
• Progression: opt for a weight range that allows gradual increase as strength improves
• Filling method: decide whether water or sand best suits your convenience and storage

Usage recommendations

Use the PEZZI Original Heavyball for controlled progressions: begin with lower fill levels to master form, perform explosive moves on impact-resistant surfaces, and inspect the seal and material regularly to maintain safe use.
