Muscles targeted
Upper abdominal

Starting position
Lie on the floor with your legs bent and your feet flat on the floor.

Movement
Lift your head off the floor. Next, pull your tummy muscles as you curl your upper body forwards in a diagonal position until your shoulder blade just comes off the floor. Return slowly to starting position and switch sides as you curl up again.

Do 10 times on each side. Once this becomes easier try to build up to 20 each side.
