Kick ass - literally

Kick boxing is also a good cardiovascular workout too. A variation of this martial art is Tae Bo - a mix of Tae Kwon Do and kick boxing steps - devised by American fitness guru Billy Blanks. The 150 devotees, who regularly queue to get into his class in Sherman Oaks, Los Angeles, include Goldie Hawn, Carmen Electra, Brooke Shields and Sugar Ray Leonard. Similar classes are now running in the UK at various gyms.

Try these kick boxing sample moves:
The Uppercut is great for improving strength and muscle tone in the upper body. Stand with your feet wider than shoulder-width apart and bend your knees so that you are in a half-squat position. Keep your shoulders down and press your heels into the floor, lifting your ribcage at the same time. Clench both fists in front of your body (with your thumbs towards you) and push off your left leg, rotating your left hip forward as you punch upwards (towards the ceiling) with your left fist until it reaches nose level. Repeat on the other side. Make sure your body weight rests in your heels so that you don't bounce too much. Perform 15 upper cuts with each arm.
