If you are practicing muscle blocks, you should slow down as much as possible when doing these movements, and your posture should be standard.

I feel that your situation is the same as the 50KG arm exerciser I used a few years ago. I just bought it and started to do it as soon as I came up. Because I didn't find the best way to exert my strength, I made 15. The next day, my wrist hurts, from my joints to my shoulders. It's been three months. It's terrible, brother.

Finally, I wish you good health and entertainment circle!
