Instructions
Preparation
- Sit on apparatus with lower leg secured under padded bar.
Hold weight to front of chest or behind neck or use no weight.
Execution
- Lower body back until hips are almost extended. Raise body
by flexing hips until torso is upright. Repeat.
Comments
- Exercise can be performed on standard
bench or without added weight. Rectus Abdominis and Obliques
only contract
dynamically if actual waist flexion occurs. With no waist
flexion, Rectus Abdominis and External Oblique will only act
to stabilize pelvis and waist during hip flexion. See Arm
Position During Waist Exercises and Spot
Reduction Myth and Lower
Ab Myth. Also see Dangerous
