Muscle mass is one of the most important factors in the work of metabolism. The more muscle you have, the better your metabolism, because muscle cells consume far more energy than fat. For example, 1 kilogram of muscle tissue daily consumes about 15 calories per day, and 1 kilogram of fat – only about 5. Do you feel the difference?
This means that a person with a large percentage of muscles in the body burns more calories, regardless of whether he is engaged in the gym or lying on the couch. Therefore, the main benefit of weight training for weight loss is improving your metabolism.
Aerobic training is an important element in the system of losing weight. Doing aerobic training, you burn fat. But at the same time you burn muscles. And without the inclusion of strength training in your fitness plan, these muscles are not restored. Roughly speaking, you lose weight, lose weight, but not only due to fat cells, but also due to muscle.
