idk if it's cause i've had lower back problems or because im short but i feel 1000% more comfortable bench pressing with my feet up on the bench. it looks really dumb but i see people do it sometimes. is there a significant difference if I bench like that vs. normal? i normally do 5x5 of heavy benching with my feet on the ground - , then just do 1 set of 10 lighter reps or something with my feet on the bench. it feels different but i cant tell for sure if its effecting the workout in anyway. any quick thoughts on this.
