Place your feet inside the straps and position yourself face down with your hips resting just off the padded platform. Grip the handles at the front.
Start by slowly lifting your legs up to begin swaying the weight to build momentum until your body makes a straight line. Drive your legs backwards on the way up but then drop them down with the weights on the way down. Keep your legs straight throughout the movement. Repeat for the desired repetitions then lower the rep ranges until the weight is still.
Avoid allowing your upper body to sway too much during the exercise.
