Your muscles have an important role to play as part of a healthy metabolism. Improper foods or excessive amounts of it and poor muscular exercise cause obesity, which can in turn cause disorders of the spinal column and joints due to their wear. This causes metabolic disorders.
Strength training has a durable effect on the metabolic activity of the muscle cells. Your muscle fibres become thicker and stronger. Previously dormant muscle fibres are reactivated. Thus, with strength training, you can improve the ratio of fat to muscle mass. Because muscles are heavier than fat, you will initially gain a little weight with strength training. This is an intended effect, because fat is burned in the muscle fibres. Due to the increase in muscle mass, you enhance your fat burning engine – it becomes more powerful and encourages a healthy metabolism.
