Instructions
Preparation
- Lie supine on bench. Place hands under lower buttock on each
side to support pelvis.
Execution
- Raise legs by flexing hips and knees until thighs are completely
flexed.. Return until hips and knees are extended. Repeat.
Comments
- 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. It may be necessary
to completely flex hips before waist flexion is possible, as
in leg-hip raise. Also see Spot
Reduction Myth and Lower
Ab Myth.
Easier
- To decrease intensity, perform exercise on floor and allow
heels to make contact with floor each repetition.
Harder
- Perform on incline board or perform with knees straight to
increase resistance. Knees can also be raise to shoulders to
dynamically involve Rectus Abdominis. Exercise can also be performed
with added weight.
