Flexibility - Trunk Extension

Trunk Extension

Procedure

1. Warm up generally (includes every part of the body).
2. Warm up specifically by stretching the trunk area.
3. Place a long ruler in front of you (vertically).
4. Begin by lying face down on the floor with the legs straight, toes pointing out and the arms by the side. Use the gym mat if available.
5. In the count of 3, slowly raise your chest and shoulders as high as you can, keeping your toes in contact with the floor at all times.
6. Hold the position and read out the reading at your eyes' level.
7. Repeat the procedure for hands behind your head and hands stretched out forward.

CAUTION! Do not force extension to avoid hyperextension. This will hurt your back.
