The reason why many people don't want to practice leg muscles is that it will be very painful not to practice leg muscles. For example, the gym has some machines that specially exercise our thigh muscles. Squat can exercise our calf muscles when running or doing some weight lifting training, but it will give people a feeling of pain after exercise, because it may be painful to walk. But it's really good to exercise leg muscles.

1. Promote the growth of our whole body muscle groups.

Exercising leg muscles can promote the secretion of hormones in our body. If our muscles want to grow, they must be stimulated by hormones. For example, if your Mamata really wants to run, someone must whip it. Our hormones are like that whip, which can make our muscles grow rapidly. Many times, we did a lot of sit-ups, but found that abdominal muscles, chest muscles, waist muscles and biceps did not grow rapidly. On the one hand, it is because of diet.

2. Promote systemic blood circulation and improve the overall strength of the body.

When our body really exerts its strength, whether it is the arms, chest muscles or abdominal muscles, it needs the participation of leg muscles. It is impossible to develop the upper body without the development of leg muscles. Leg muscles must exert strength to really complete a series of strength movements. For example, when doing sit-ups, our thigh muscles will inevitably tighten, and when doing pull-ups, our leg muscles will struggle, although not as strong as arms and legs.

There are many other benefits when the leg muscles are really developed, such as increasing the ability of long-distance running, increasing the endurance of men, promoting the blood circulation of the body, making the whole person's skin better and blood circulation faster, countless, but it is very painful when exercising.
