The light green Merco FitGym overball is a practical exercise aid for adults. Thanks to its flexible PVC surface, it responds to pressure, and its firmness and exercise difficulty can easily be adjusted by changing the amount of air. It is suitable for therapeutic, compensatory and fitness training.
You can place the ball under your back or pelvis, or squeeze it between your knees or palms. During slow and controlled movements, it supports stability, core activation and coordination exercises. It can also be used for stretching or after prolonged sitting.
