1 - Find a comfortable floor.
You should use a comfortable mat, a gym floor at your gymnastics school, or a floor with some cushion to do a somersault. If you use a hard surface, such as a wooden floor, then you're more likely to injure your head and neck.

2 - Stretch well.

You should stretch before you perform any gymnastics skill. For the somersault, there are a few key parts of your body that should be stretched well before you begin so you don't sprain a muscle or hurt yourself. Here's what you should do;

3 - Stand with a straight body.

Stand straight up with your hands reaching up and your arms by your ears. Your palms should be facing out, slightly to each side. Your legs should be close together and there should be a slight arch in your back, with your head facing straight ahead of you. This is a classic beginning stance in gymnastics. If you feel more comfortable starting on the ground, however, you can skip this starting position and move straight to the floor.

4 - Crouch down.

Tuck your legs and place your hands on either side of your feet, facing forward and several inches in front of each foot. Your chest should be resting on your thighs. Round your back and put your head down so that you're looking at your belly button. Remember that your head should never touch the ground in a somersault; holding this position will help keep your head above the ground. You'll actually be landing on your upper back, not on any part of your head.

5 - Push off through your legs.

Lean forward as you push off through your feet and legs and make your hips come up over your head while your hands stay on the ground. Your arms and legs should straighten while still being a little bit bent as you roll forward and land on your back.

6 - Continue to roll forward.

Remember that your head and neck should never touch the ground; as you continue to roll, your upper back will touch the ground first as you roll onto the rest of your back before you come up. As you roll, keep your shoulders straight and even; if one shoulder moves before the other, you could hurt yourself and won't land the somersault in a straight position. No jumping is necessary to do a somersault -- in fact, this could cause injury -- all you need is to roll forward using the momentum generated by your legs.

Follow through. Your legs should be tucked as you finish the somersault, and you should land on your feet with your arms straight out in front of you.

7 - Stand up.

To finish the somersault, you should roll onto your feet and use your momentum to stand straight up, with your arms all the way up and your body straight once more.
