Stretches

Remember, you should never feel pain when you stretch. Obviously, there will be the slightly uncomfortable burning feeling as you stretch your muscles, but if you feel pain stop. Stretching incorrectly can lead to injury. However, not stretching at all can lead to injury too. Ensure you are always warmed up before you dance.

Legs

Sitting, legs apart, arm over head to touch foot. Try and get your chest on your thigh.

Sitting, legs apart, reach out to touch foot. Try and get your chest on your thigh, and hands beyond your foot.

Standing, feet together, touch the floor.

Sitting, put the bottoms of your feet together, get your feet as close to your body as possible.

To increase stretch:

or

Put your head on your feet.

Back

On your hands an knees, arch your back down and look up, hold, then arch you back up and look into your body.

Lie on your front, push your body up, and look up, keeping your hips touching the floor. Start with your legs slightly apart, then bring them closer together a little more each time.

Do a bridge. I'd recommend, when warming up, you push up from the floor. Once you are warm you can go in from standing.

Arms

Swing arms around in circles both ways. 

Similar stretches: Hands on shoulders, circle elbows. Or, just circle/roll shoulders.

Put your arms behind you, palms together, raise your arms. Try not to lean forward.

Put your arm across your body and apply pressure on your upper arm with your other hand. Do not apply pressure on the elbow joint.

Put your hand on the back of your head then pull your elbow with your other hand.

Other

Look to the sides, up and down. Roll your head. Rest your head to the side, apply pressure to your head with your hand. Do not bring your shoulder to you head.

Put your hand on your hip or waist. Lean and stretch your other arm out.
