the thing that bothers me alittle is u will c a guy with 405 on the bench or even 315 n hes screaming doing the reps but u see a guy spotting him getting a huge trap workout,then the guy benching gets done n ask the spotter u didnt barely help me did ya,n the spotters trying to answer in the midst of catching his breath from the ruthless upright row set he just did n says,no not at all,lol.my theory is if u cant lift it off yourself n bench it yourself its to heavy,EGO is a killer in the gym
