Lying Leg Raise (on floor)

Instructions

Preparation

Lie supine on mat or floor. 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, allow heels to make contact with floor each repetition.

Harder

Perform on bench or do not let heels to make contact with floor. For greater resistance, perform on incline board or with knees straight. Knees can also be raised to shoulders to dynamically involve Rectus Abdominis. Exercise can also be performed with added weight.
