Instructions
Preparation
- Position body on padded parallel bars with hands on handles,
back on vertical pad, and body weight supported on forearms.
Execution
- Raise legs by flexing hips and knees until thighs are just
pass parallel to floor. 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; see
Weighted
Vertical Leg-Hip Raise. Also see Spot
Reduction Myth and Lower
Ab Myth.
Easier
- Lie on flat surface or incline to make this exercise less
intense.
Harder
- Exercise can be performed with added weight. Knees may be
kept extended throughout leg raise to increase intensity. Knees
can also be raise to shoulders to dynamically involve Rectus
Abdominis.
