The basic sit-up is a popular way of working your abdominals.
Strong abdominals give you a good core strength, essential for all sports.
Start off by lying on your back with your knees bent, making sure your feet are flat on the floor.
STEP ONE
Bring your feet in towards your bottom and lock your hands behind your head.
Try to keep your eyes on the ceiling even when you pull forward.
STEP TWO
Bring the shoulders and the upper body up towards your knees.
Come up to an angle of no more than 45 degrees - there's no need to go further than this.
Make sure you are working the abdominal muscles and not the hips.
Try to keep your chin off your chest and keep your elbows out by your sides.
