Easy to carry and can train at any time. Lightweight, it is a training tool that you can carry with you.
It has nothing to do with gravity and can rotate freely. The resistance comes from the stretch of the elastic band rather than the gravity of the earth. It is more free and changes during training.
There is no inertia, no motivation, no power. Since the resistance provided has nothing to do with gravity, you can't use strength during training, and the training effect is better.
Can imitate daily movements and improve functionality. The elastic band training can be performed in any posture and in any plane, and the function is more powerful.
