i joined a gym a few weeks back. got tired of lifting weights outside. anyway, i see these younger guys (18-22 age) that load up the bar and only do partial reps. not like the ones that are for isolation and you start at the bottom and go halfway, they are starting at the top (arms fully extended) and then bringing the weight down maybe 6 inches from their starting position and back up and locking out and that's one rep , basically just bending their elbows. these guys probably weigh 140 pounds and are moving 160 pounds not benching 160 pounds. i would guess that they couldn't even bench their own body weight. i guess it is just a pet peeve of mine but if you are going to take the time to go workout, make the workout count.
