1. The gym will not be exposed to the sun unless it is windy. You can go as long as you have time, and you will encounter many restrictions outdoors.

There are many equipment and other courses in the gym, such as yoga, spinning, belly dancing and so on. It not only enriches the form of exercise, but also won't be boring.

3. Fitness should be combined with anaerobic and aerobic. Running is aerobic, and aerobic exercise takes at least 30 minutes, which depends on your physical fitness, so you don't know when you run out of sugar and start burning fat. And only doing aerobic exercise is easy to consume muscles. The purpose of fitness is to reduce fat, gain muscle and shape lines. So in the gym, you can practice equipment first to do anaerobic and then aerobic, which is more scientific and helpful to lose weight.
