The purpose of most people's fitness is to lose weight or exercise muscles. The goddess wants to lose weight more. Although boys want to exercise more muscles, they have to lose weight first. But there are always many girls who complain or worry about whether running or other fitness methods will thicken their calves or arms. Because we girls in China generally don't like to exercise muscles, as long as we are thin enough, it is their pursuit to exercise slender arms and calves.
Suppose a girl consumes a lot of fat after a long run, but at this time, you will find that your calf becomes hard, and the shape of the muscle is highlighted, becoming stiff and firm. At this time, it is necessary to stretch in time, which can speed up the local blood circulation of the calf, transport metabolic waste in time, and then relax the muscles so that they are no longer so hard.
Like long-distance running, other fitness methods also rely on muscles to do work, which will inevitably make muscles hard. If you don't stretch for a long time, the fat will decrease, but the muscles will become strong, not slender, but short and strong. So girls should know that stretching after fitness is not only related to the effect of exercise, but also affects the shape of legs and arms.
Of course, not only girls, but also boys, most of them expect their legs not to be too thick and their muscles to be more stylish, but their leg muscles are better coordinated. And we should also pay attention to simple warm-up exercises before fitness, especially for boys who want to do strength training. They should not be overloaded at once, and they are easy to strain.
