Motion description

The expander is securely attached in front of the body. The two ends are wrapped around the wrists and held tightly in the hand. The upper body is in a light upper body template. In order to allow the spine a larger contact surface, the athlete stands in a step position. The hands are stretched in front of the body at shoulder height. The expander is already pre-stretched.

In the execution of the movement, the expander band is guided to the side of the body. the upper body moves as little as possible. All movement must be slow and controlled. To ensure safety during training, the flawless condition of the expander must be checked before each training session.

Safety during expander training

Even if the expander is not a weight, this form of strength training is not without danger. In many exercises, there is high tensile resistance, which can cause the expander band to tear. Before training, you should therefore always check that the expander is in perfect condition and replace it if necessary.
