any overhead pressing movement, I've maxed out a bunch of machines, I've dont he 110lbs dumbbells but I train by myself so just getting them up into position was a bitch, I didn't try to go any heavier. When I press on the smith I set the stops to just below my nose, I've got a wrestling injury so if I go really deep my shoulder aches for days, not the good "sore" ache the it really f'n hurts for me to move my arm ache. Anyway, I can do 275ish on the smith for reps that way. I've done a ton of weight on all the hammer rowing machines-I've maxed a few of those out and don't even bother with them anymore, I've done over 900lbs on the legpress for reps, I've done 6 reps with an 80lbs dumbbell for 5 reps doing dips.....a few years ago I was really into deadlifting but I did them more in the "sumo" fashion and did 495 for reps....
