Sprinting works your fast twitch muscle fibres and helps to build muscle size

Posted June 29th, 2009.

Have you ever admired the physiques of sprinters and wondered how they can get so muscular and lean? Whilst its no secret that genetics play a part there is something that can be leant from the way they train and look. For anyone interested in weight training, combining interval training into your overall workouts can help you develop that lean and refined look. Activating the fast twitch muscle fibers helps to build muscle size and also stimulates your metabolic rate. When you raise your metabolic rate you also burn fat. When you strip away the fat you start to see the definition come through in your body.
