Instructions

Lie face down on the floor, resting on your forearms. Keep your legs together and your spine in a neutral position. Raise your body up on to your forearms and toes. Be sure to have your elbows and shoulders aligned. Keep your body straight without allowing it to sag. In this position, bend one knee until it touches the floor, then bring it back up. Repeat with the other knee. Keep alternating until all required repetitions are performed.
