Good to know, but I am so not sharing a rack with anyone, haha! My workout, my rack https://startingstrength.com/resources/forum/cool.gif
We schedule out workouts on separate days. Mine take about 2 hours to complete since I use up to five sets of triples on most movements (except for the press, amazingly). His workouts are quite long too because he has yet to stop adding mirror-muscle high-rep silly bullshit to the program. I refrain from giving him a hard time about it; what he does now is still a huge improvement from what he was doing before.
I trust that he will eventually come to his senses. Proportionally to our respective bodyweights, my lifts are higher than his (except for the bench), and I know this bothers him already. All I have to do to convince him that the program works as it is to keep improving my numbers.
