Exercise ball HMS Fitness YB03 65 cm Grey Full-size 230 kg

The HMS Fitness YB03 exercise ball is a full-size 65 cm grey training ball designed to support users up to 230 kg. Made from special anti-burst rubber, the ball gradually loses air in case of puncture to reduce the risk of a sudden fall. One hemisphere features raised lugs for soft self-massage during movement, while the textured surface helps prevent slipping and improves grip during dynamic and static exercises.

Advantages

The YB03 combines a high load capacity with anti-burst construction for enhanced safety during intensive use. Its non-slip structure and lugged surface support secure positioning and provide gentle muscle stimulation that can assist recovery and reduce discomfort from micro-injuries. The 65 cm diameter places this ball in the full-size category, making it suitable for a wide range of balance, stability and core training exercises.

How to use

Inflate the ball to the recommended firmness using a compatible pump until it reaches its intended shape and stability. Choose a size-appropriate ball for your height and training goals; the 65 cm diameter suits most full-size applications. Use the ball on a flat, clean surface and perform exercises such as seated balance holds, plank variations, leg curls, bridges and controlled roll-outs. During rehabilitation work, follow guidance from a physiotherapist or trainer to set repetitions, range of motion and intensity.

Usage recommendations

Inspect the ball before each session for signs of damage or excessive wear. Clean with mild soap and water and avoid sharp objects, hot surfaces and direct prolonged sunlight. Store the ball deflated or partially inflated in a cool, dry place if not used for long periods. When used as part of therapy, follow a professional plan and stop exercise if you experience sharp pain or dizziness.
