Bulking up for blokes
There is no magic nutrient — hormone, drug or protein powder — that will effectively increase your muscle mass without exercise. The only way you can increase your muscle size is by stimulating growth at a cellular level. The best way of achieving this is by following an individually tailored weight training program plus a diet that gives you increased energy. By combining diet and weight training you can expect to increase your body mass by about 0.5kg per week.
