Spiderman push-ups

Instructions

Get into a face-down position on the ground, supporting your weight on your toes and your hands slightly more than shoulder-width apart.
Bend your elbows to slowly lower your body until your chest is close to the ground. At the same time, raise your right knee to the side and try to make it touch your elbow.
Hold this position for one second, then go back to the starting position.
Repeat with the other leg.
