Half Balance Ball is statically trained to maintain a constant breathing for 45 seconds - 60 seconds. Dynamic training can also be done, centered on the sphere, and the torso can be angled up and down. When the trunk is down, it is parallel to the ground. When the trunk is up, the torso and the thigh should be at a 90 degree angle. Pay attention to exhale when you go up and inhale when you are down. 2 to 4 seconds down and 2 to 4 seconds to center.
Although the exercise of the Half Exercise Ball is relatively small and relatively simple, maintaining balance is a difficult point. Everyone must concentrate on their efforts to control their muscles while exercising. Only in this way can we exercise more muscle fibers, make our body more harmonious, firmer and look slimmer.
