1. Improper adjustment: the grip part of the fitness circle can be adjusted to suit hands of different sizes. If the grip is adjusted too tightly, the grip will be too tight. At this time, it is necessary to check the adjustment part of the grip to see if it can be loosened or adjusted.
2. Improper use: The grip design of some fitness circles is elastic and needs to be held and used correctly. If the grip is incorrect or too hard, it will lead to a tight grip. At this time, you need to pay attention to the posture and strength of the grip and relax your hands.
