Lifting sticking points

For both bench press and overhead press, my sticking point is in the middle.  Pretty much when my triceps are parallel to the floor.  Due to this, my next lifting cycle will incorporate floor pressing.  Provided I can figure out a way to do it at the gym.  At home, I can press in the rack.  At the gym, the j-hooks are too deep to pull the bar out (they are actually "J" shaped, with about a 2" deep cup).
