Welcome!
The resistance of the elastic band is calculated in kilograms according to its percentage elongation at relative rest. During the elastic band training, we can evaluate the resistance of the training according to the change of the length, and we can also select the appropriate length of the elastic band according to our own situation.
The elastic belt has no inertia, no power, and cannot borrow force. Since the resistance provided has nothing to do with gravity, you can't borrow force during training, and the training effect is better. Elastic band can imitate daily movements and improve functionality. Elastic band training can be carried out in any posture and any plane, with stronger functionality.
