Else jump in for a set. I recently got a couples membership as I thought the pool would be nice as my wife recovers from her total knee. I do five or six different machines and like to do one set on each and go around and come back for a total of 3 sets each device Inevitably there’s one kid sitting they’re not moving for 5 to 7 minutes on his phone most of the time Doing nothing as he does his 3–4 sets not letting anyone else access the machine the whole time he’s sitting there on his phone

For squats I generally tell my patients with anterior knee pain to stand with their backs against a wall and only go down to where they can’t see their toes anymore maybe 30–40° of knee flexion otherwise it may not be the best for your anterior knee pain

Also, I end up doing a lot of total shoulder replacements for guys who spent too much time doing heavyweights on bench press
