There's no evidence that high repetitions—doing lots of reps while weight training—will burn fat. However, strength training in general can help you lose weight and keep it off. That's because muscle burns more calories than fat, even when you're resting. So increasing your body's muscle, which scientists classify as lean body mass, can be an effective long-term approach to weight control.

Combining high repetitions with lighter weights can potentially reduce body fat. Stored body fat is simply an accumulation of unused calories, from consuming more than you have burned. This is known as the Law of Thermodynamics. You body is designed to conserve energy. When you consume more calories than you need, your body will store these excess calories as body fat. In order to reduce body fat you must reverse the trend and burn more calories than you consume. A great way to burn more calories is exercise, including strength training. Performing resistance training, will allow you to burn more calories, and invariably stored body fat, during the activity as well as after. In addition, it is advised to reduce or your caloric intake and eat a healthy sensible diet.
