Sit on the edge of a solid chair and hold the front edge of the seat on both sides of your body. Your knuckles should be facing forward, not turned to the sides. You can either plant your feet firmly on the floor or place the backs of your ankles on a bench in front of you so that your buttocks are suspended in the air.
Push yourself off the seat and lower your buttocks below it until your arms form a 90-degree angle. Then, push yourself back up to the starting position, but make sure not to lock your elbows. Repeat until you can't do any more. Then do two more sets of the same.
