Of course, it is not necessary, but it is ok to have a certain source of income, and the effect is much better than my own practice. However, if I have three months free time, I can lose fat, and my abdominal muscles and chest muscles can be obvious! ! Do you need to go to the gym for such a long time as three months? Besides, it's summer vacation! In such a good month, running can lose weight every day, and push-ups can enlarge your chest muscles every day. Are you afraid that you will lose your strength after three months of fitness? Bad figure?

Believe me, instead of going to the gym, the gym is at home! ! !
