Start by lying on your back on a decline board that is set up against a wall ladder.
Take hold of a wall ladder above your head.
Extend both of your legs out in front of you so that your hips are at 90 degrees and your legs are straight.
Press the small of your back flat into the decline board.
Drop one of your legs out to the side, keeping it straight through the movement.
Return to the start position and repeat with your other leg.
