The source of resistance of the elastic band mainly changes based on its elongation. Elastic band elastic resistance training is a very special kind of resistance training. When using elastic band training, users can train most muscles of the whole body in any position and posture, which is more convenient and effective during training.
The resistance of the elastic band is calculated in kilograms based on its relative elongation at rest. In the training of elastic bands, we can evaluate the resistance during training according to the change of length, and we can also choose the elastic band of appropriate length according to our own situation.
