If you work in pairs, you have to push even if you push one. You must get used to this weight. After pushing a few more groups (3-4 groups), you should lose some weight (7-8 pushing groups in each group) and stick to it. Then, after exercise, you must eat well (high-calorie food plus protein), rest, and don't stay up late. Then you can keep it like this for a month to ensure that you can get up (strength chest weight).
