|Utility:||Basic or Auxiliary|
Position thighs prone on padding. Hook heels under platform lip or padded brace. Hold weight to chest or behind neck.
Raise upper body until hips and waist are fully extended. Lower body by bending hips and waist until fully flexed. Repeat.
If weight is positioned behind head, neck extensors act as stabilizers
See Arm Position During Waist Exercises. Position pad high enough to evenly distribute body weight on thigh but not so high that range of motion is limited; abdomen should not press on top side of pad when upper body is lowered. Begin with body weight and add additional weight gradually to allow lower back adequate adaptation. Do not pause or bounce at bottom of lift. Do not lower weight beyond mild stretch throughout hamstrings and low back. Full range of motion will vary from person to person. Also see Weighted Back Extension and Weighted Back Raise.
