Apr 25, 2017 This is where I completely disagree. I won't let someone I don't train with "work in" with me. You're either a training partner training with me or you can sit and watch me lift. One of my training partners made this mistake and it got him hurt. They don't pay attention, don't load the bar correctly, don't spot correctly, etc.... If I don't know you, you're not working in with me.
