1. Reduce fat and gain muscle. Strength training experts have done a lot of strength training research on thousands of women, and have not found that any woman will develop muscles because of moderate muscle strength training. Women who do strength training three times a week gain an average of 1.75 pounds of muscle and lose 3.5 pounds of fat after eight weeks of persistent exercise. Unlike men, women generally don't develop their bodies through muscle strength training, because the hormone level of developing muscles in women's bodies is only110 to 1/30 of that of men.

2. Muscle gain helps to lose weight. With the increase of muscles brought by muscle strength training, the metabolic rate of the body at rest will gradually increase, so you will consume more calories every day. Studies have found that every time the body increases 1 pound of muscle, it will consume 35-50 kilocalories every day. ?

3. The research of strong physique shows that moderate strength training can improve the muscle strength of human body by 30-50%. The enhancement of strength will not only make it easier for people to finish some daily work, but also make people full of energy and vigor.

6. Make friends and increase your vitality. Of course, there will be people in the gym who share your interests. Make a few friends, and you will find that under their leadership, fitness is no longer a boring physical activity. More often, you will actively participate in it, and life will naturally be full of vitality.

Disadvantages of going to the gym: Some gyms have poor air circulation, because many people can't breathe fresh air, which has little effect on improving their health. Gyms are for profit, and of course they cost much more than outdoor free sports. Of course, having professional guidance in the gym will get twice the result with half the effort, but not all events are suitable for everyone, and the timing is not necessarily a coincidence.
