Is it necessary to go to the gym to exercise?

If you have a high demand for shaping, it is very necessary to go to the gym. If you just want to lose weight, you can adjust your diet+run in the community or ride a bike at home. Remarks: Aerobic diet can make you thinner, but not more stylish! For example, the buttocks are only aerobic and can't reach it! So if you really want to get in shape, you'd better go to the gym to practice comprehensively.
