How is it done?
Pre-stretch the area where the cup is to be placed using a classic stretching exercise. Place the cup and hold the stretch to increase the local stretch.
Tip: If it is not possible to place the cup firmly in the stretched position, you can place the cup first and then go into the stretched position.
What happens?
Structural shortening, especially in the back and neck area, can benefit from this technique. Expanding is also good for mental tension.
