I have a two station gym at home and each station has 150lbs weight stack (10lbs each plate).... With the resistance, some workouts can bring up to 360lbs on one stack........ Say if I was going to do front presses, I could set my pin on the hole stack of 150lbs and with the resistance it's really 240lbs....... The Leg press station can resist at 360lbs on a 150lb stack.
