Instructions
Preparation
- Sit on floor or mat. Lie supine with hands to sides.
Execution
- Simultaneously raise knees and torso until hips and knees
are flexed. Return to starting position with waist, hips and
knees extended. Repeat.
Comments
- Begin each repetition with upper back on floor to allow abdominal
muscles to work dynamically. The Rectus Abdominis and Obliques
dynamically
contract only when 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.
