Muscles targeted
Upper abdominal

Starting position
Lie on the floor with your legs bent and your feet flat on the floor. Rest your hands on the back of your head or rest them on your thighs.

Movement
Lift your head off the floor and pull in your tummy muscles as you curl your upper body forwards. Don't pull on your neck when you come up. Keep your lower back flat on the ground.

Do this 5 times. You can gradually build up to 20 with practice.
