I gained weight for three months and gained 24 Jin. Diet, high protein, high calorie diet. Concentrated protein and high-calorie foods, such as heavy cheesecake, small cakes, small cakes, etc. Papain or comprehensive enzymes should be supplemented in time after meals to help digestion, so as to increase the digestion, absorption and utilization of food. In exercise, "weight training" is the main way to increase muscle proportion. With the help of dumbbells, barbells and training equipment, combined with the complete contraction and relaxation of large muscle groups, muscle construction can be realized. For specific fattening methods, I recommend you to go to Shangmei Fattening Network (/), the first professional information website in China. It was there that I learned how to gain weight successfully. I wish you success in gaining weight!
