before we had the bumpers, what used to crack me up is people playing muscial chairs with the plates on the seated shoulder press station.
You would either have the guy who . . .
Warms up with the bar, put 25's on and does 6-8 reps. Takes 25's off and puts 35's on. Does 5 reps. Takes 35's off and puts 45's on and does 4 shitty 1/2 reps, for 4-6 sets.
OR
The guy who warms up with the empty bar, goes straight to 135, which he barely can do for 4-5 shitty crooked 1/2 reps.
Anything to go from 0-135 as fast as possible.
No one could stand to use 25's with some 10's and/or change plates.
NOW, that we have the rack w/ bumper plate tree on the side.
Everyone does standing OHP w/ 18" dia 10's & 25's on the bar . . .for many more reps
