Another point I wanted to make with it is you might be strong enough to rep 225lb+ out 5 or more times or more than 10 or whatever. The thing is getting your connection points acclimated to that range and testing them safely instead of tearing something.
"practice safe sets"
I worry about catastrophic injuries all the time and the risk vs reward of all this. Hahhahah.
There's a good chance I will never do it. I don't have anyone to spot me and there is no way I would try anything alone. I'll just stick to using the total gym and doing the occasional push up.
