The Superset is an excellent intensity technique not only for fat loss but for muscle building as well.A muscled strong body will respond better to nutrition. Your metabolism will convert your food to useful energy, not fat. Ideally you feed your muscle and starve your fat.The superset is a very simple concept, basically you just do two exercises back-to-back, with no rest inbetween!The weight is light enough that you can do a dozen repetitions of an exercise. Start out light. You can always increase the weight.
Super sets start with seven basic exercises. These exercises can be changed or modified to suit your equipment and space.

Bench Press
Horizontal Flies
Upright Rowing
Lat Pull Downs
Curls
Tricep curls
Squats

So, do 12 Bench Presses, then 12 Flies, then 12 Upright Rowing etc. until all of the exercises are done. If you can`t do all do 12 of each one then you should reduce the weight.It is easier to start light and move to heavier weights on another day.
After a 1-2 minute break do 12 reps of each exercise again (this is the second set).After that do a third set and when you finished with all the sets that meaning 3-4 sets, take a 2 to 3 day break, so the muscle can grow. In the day that you do the superset weight training eat more calories to have energy, and the rest days you should eat plenty of protein and carbohydrates ( don`t forget about the water).
After you get used to the light weights, use heavier ones, and change the exercises as you want.. do some abs exercise for example instead of curls etc.
Supersets increase Lactic Acid production, which helps boost Growth Hormone (GH) levels in the body. The body responds to the reduced pH (increased acidity) in the body from the production of Lactic Acid by secreting GH. GH is a powerful fat loss and muscle building hormone.
Try it, you will not regret it !
