Instructions
Preparation
- Stand between parallel bars and grip bar on each side with
overhand grip. Lift body off floor and balance body upright with
arms straight.
Execution
- Raise legs by flexing hips and knees until hips are fully
flexed. Continue to raise knees toward shoulders by flexing waist.
Return until waist, hips, and knees are extended. Repeat.
Comments
- This exercise is alternative to Vertical
Leg-hip Raise when apparatus is not available, or Hanging
Leg-hip Raise when high bar is not available or too low to
allow for adequate leg clearance. Rectus Abdominis and Obliques
only dynamically
contract only if actual waist flexion occurs. With no waist
flexion, Rectus Abdominis and External Oblique will only isometrically
contract to stabilize pelvis and waist during hip flexion;
see Weighted
Vertical Leg Raise on parallel bars. It may be necessary
to completely flex hips before waist flexion is possible. See
Spot
Reduction Myth and Lower
Ab Myth.
Easier
- Movement can be made easier by performing exercise on incline
board.
Harder
- Exercise can be made more challenging placing weight between
ankles
