You can change the amount of air according to your individual needs. With a high amount of air, the half-ball in the ground area bulges and the trampoline effect (vertical vibration effect) increases. With a small amount of air, a clear seat is created, the half-ball becomes flatter and the rocking effect increases. To reduce the amount of air, you remove the needle from the side of the handle of the pump, insert it (without a pump) into the valve and then press on the half-ball. If there is an unpleasant ball under the buttocks, you should sit on the ball further forward or change the amount of air. With a small amount of air, you can also sit on the flat side of the half-ball. To optimize the sitting posture, you should sit more in the front area of the half-ball.
A ball arch about the width of the hand then arises behind the buttocks. Most people sit too deep. The optimal, open seat angle is 110 ° to 120 ° between the trunk and thigh. By regulating the amount of air, the seat height on the half-ball can be optimized accordingly. The half-ball is a seat alternative for back training in between. You can increase your seat duration with improved training condition.
