First of all, we must balance our diet. If we eat a reasonable and healthy diet, we won't exercise often and we won't lose weight.

Then there is the method and frequency of your fitness. Don't do too much exercise every day, just two hours or so. Also, if you want to exercise your weaknesses, such as chest muscles, you should do more push-ups and forward bending of your arms. Moreover, the posture of the movement must be standard and the movements must be in place. My classmate's abdominal muscles are asymmetrical because of twisted movements. Another classmate didn't do push-ups well, and as a result, he still had a flat chest after practicing for a long time. Hmm. How interesting

Basically, a pair of dumbbells, an arm strength device and a tension device are prepared at home. Hold it.

The muscles of the upper body can be exercised.
