Although doing aerobics has many benefits, such as: exercising and improving heart and lung function, enhancing human metabolism, enhancing immunity, consuming excess calories and so on. Doing aerobic exercise consumes a lot of calories, which is more obvious for losing weight and fat. Anaerobic training needs calories, and anaerobic training focuses on muscle gain. The process of muscle repair after excessive exercise, that is, the process of muscle growth, needs more calories, and of course, it also needs enough nutrients such as protein and carbohydrates. Therefore, if the body is thin and the purpose is to gain muscle and weight, you can temporarily not consider doing aerobic. Emphasis should be placed on equipment practice and daily nutrition supplement. If you are not going to take sports supplements, then try to turn yourself into a foodie, hehe. Strength training For ordinary amateurs, 1.5 hours of full-load training is a reasonable time range. Professional bodybuilders seldom do aerobic exercise during non-preparation.
