Your goal in weight gain is to increase muscle mass without gain in body fat.
You must increase caloric consumption; increasing protein intake and
carbohydrates. Also you must incorporate a resistance program using weights
where you overload the muscles and increase resistance and stimulate
white-fast-twitch muscle fibers.
The following programs can benefit in weight gain:
· Bodybuilding
· Free-weight Training
· Circuit Training
· Body Pump – Weight Cardio Program
