I am thin. Can I jog after fitness? I want to improve my physique. Jogging is good for me. But will you lose your muscles and practice for nothing? Just run three kilometers?
Running will not lose muscle, and the number of human muscles is fixed. Running can make the whole body get exercise. Correct running can increase vital capacity, exercise viscera, improve people's physique and enhance disease resistance. Adults who exercise for half an hour every day can also relieve stress and depression. Running can burn excess fat, develop muscles, increase muscle strength and shape a perfect figure.
