So called most dangerous gym
One man dropped weight on feet then continued lifting with blood visible through socks and was told they do not need all ten toes and finished set before going to hospital then ended up missing a toe

Person learned they could lift more weight and more reps in a row without a break then they thought they could
I do not endorse this training method but watching it is educational about how a lot of people do not live up to their potential
