Exercises with a ball are gaining more and more popularity because they can be performed both in the gym and at home. The ball is extremely useful, and its effectiveness is due to its round shape, which provides instability to the body. As a result, the muscles of the torso are activated in an effort to maintain balance. Over time, these muscles gain strength and flexibility, and you will be able to intuitively trust them in times when you need good balance. In addition, with ball exercises, you train the mid-body, which contributes to the development of general limb strength, keeps your posture good and makes the body more flexible.
