I'm on winter break right now, so I've been back and forth between school and home pretty regularly. At the gym I train at school, it feels like the bench is higher, and I'm having a lot of trouble getting tight. At home, I'm able to close-grip bench the same weight I used last at school. Anyone notice a different in bench heights? I know it might just be a comfort issue mentally, but i really can tell a difference. Any ideas?
