Rack pulls used to be one of my favorite pull variations. That was before I trained at a gym that doesn't have a designated 'rack pull bar'. I try my best to be respectful and not let the bar make more than a soft 'ting' at the bottom. I'm not always super successful in making that happen, but I damn sure try my hardest. This makes it exponentially harder, but hey, at least I'm working on the eccentric.
