Dude, this is almost the same as me. . . Exercise more hands. . . Single parallel bars. Dumbbells. Arm press-ups, anything. But stick to it. If you really can't persist, you will take turns to go into battle. We should control the quantity first. . . Personally, I like running. Instead of running with strength, you should use your heart, which is commonly called fatigue transfer. I believe you will become a tough guy after a while.
