Exercise is good for all parts of our body.
The first is the lungs. Exercise can increase our vital capacity and improve the level of oxygen utilization.
The second is the impact on the cardiovascular system. When you can keep exercising for a long time, the volume of your heart will increase, and the quiet pulse and exercise pulse will decrease. The quiet pulse is the normal pulse, and the exercise pulse is the pulse after running. They will all decrease, the speed will decrease and the elasticity of blood vessels will increase. Many elderly people around us are fragile and easy to rupture, so vascular elasticity is very important.
It is best to suggest that you run when the sun rises in the morning. Please adopt it.
