I have several years of fitness experience, welcome to discuss. Generally speaking, not going to the gym can reduce fat, but it is difficult to gain muscle. Simply put, reducing fat means that you consume more calories in a day than you do in a day. Normal people spend about 1800-2000 a day. As long as you consume more than, you will lose weight and fat. As for the method, if you don't go to the gym, you can take indoor aerobics, squats, outdoor running, cycling and other sports to reduce fat. However, muscle exercise needs professional equipment to cooperate with fitness plan and diet plan. If you practice muscles blindly, the local size of muscles may be uncoordinated, which will affect the appearance. It is more common to exercise the legs and back with two shoulders. Therefore, it's better to go to a professional gym to lose weight and gain muscle, and exercise for all. There is never a shortage of partners on the way to fitness. Burn the road for the perfect figure in your heart!
