Answer 1

Side Ups:

Side-ups. Lie on one side of your body with your feet anchored to the floor and your hands behind your head. Beginners should keep the bottom arm at the side and fold the top arm over the chest. Slowly lift your head and shoulder off the floor and then return to starting position. Then switch sides and try it again.

Front Ups:
