Gym Ball Master 26 cm by Master — 26 cm diameter, anti-burst exercise ball

The Master Gym Ball 26 cm is a compact exercise ball designed for seated balance, core activation and targeted rehabilitation. With a 26 cm diameter it fits small spaces and supports controlled movements for pilates, physiotherapy and light strength or stretching routines. The ball incorporates an anti-burst construction that limits the risk of sudden rupture and allows gradual deflation if punctured, improving safety during supervised training.

Advantages

The small 26 cm diameter provides precise support for seated posture work and targeted muscle activation without occupying much space. Anti-burst material increases user safety by preventing abrupt failure and enabling slower air release if the surface is compromised. The ball's resilient surface offers stable grip for controlled exercises, and its low-profile size is suitable for use on chairs, benches or therapy tables.

Suitable for

• Pilates exercises focused on core and pelvic stability
• Physiotherapy and rehabilitation sessions requiring targeted support
• Seated posture training and balance practice
• Light stretching and mobility routines
• Small-space home workouts and office ergonomics

Key specifications

• Diameter: 26 cm
• Intended use: fitness, rehabilitation, core stability
• Construction: anti-burst design for gradual deflation upon puncture
• Surface: textured for improved grip during exercises
• Material properties: resilient, elastic PVC-type material suitable for low- to medium-load activities

How to use

Inflate the ball to the recommended firmness so the surface yields slightly under weight but remains stable for seated exercises. Use the ball on a flat, clean surface and ensure it is properly secured when performing balance or rehabilitation movements. For seated posture work, place the ball on a chair or bench and sit with feet flat on the floor, engaging the core to maintain upright alignment. During physiotherapy or pilates, perform controlled repetitions and avoid ballistic movements; stop exercising if you detect a rapid loss of air or visible damage.

Usage recommendations

Store the ball away from sharp objects and extreme temperatures. Check the ball regularly for surface wear and maintain inflation at the level recommended for your exercise type. For safety during rehabilitation, use under the guidance of a therapist and follow weight and movement guidelines suitable for the user's condition.
