How to use

Inflate the ball using the supplied hand pump until it reaches a firm but slightly yielding feel appropriate for comfortable seating or exercise. Insert and secure a plug after inflation. Position the ball on a flat, non-slip surface and sit or perform exercises with feet flat on the floor to maintain stability. For therapeutic stretches or workouts, use slow controlled movements and engage the core to maximise effectiveness.

Usage recommendations

Regularly check the ball for signs of wear or damage and ensure plugs are securely seated before each use. Use the ball on clean, smooth flooring and avoid contact with sharp objects. For desk use, adjust desk and chair heights as needed to maintain ergonomic alignment: hips slightly higher than knees and forearms parallel to the work surface.
