Instructions
Preparation
- Hook feet under foot brace and lie supine on incline board
with hips bent. Hold plate on chest with both hands or use no
weight.
Execution
- Raise torso from bench by bending waist and hips. Return
until back of shoulders contact padded incline board. Repeat.
Comments
- Exercise can be performed without
added weight until more resistance is needed. Elevate incline
to increase resistance. Elbows can also raise up over knees during
each Sit-up to increase range of motion. Also see Arm
Position During Waist Exercises. If no knee support is built
in to incline board, ball can be placed under legs as illustrated.
If upper back does not come completely down at end of movement,
abdominal muscles may only be isometrically
involved in exercise. Pectineus, Adductor Longus, and Brevis
do not assist in hip flexion since hips are already initially
bent. Knee flexors may be involved as stabilizers if incline
is steep and no calf support is used. See Spot
Reduction Myth. Also see Dangerous
Exercise Essay.
