Stair Climb: The candidate uses a StepMill stair-climbing machine while wearing weights comparable to the equipment a Firefighter carries. The candidate walks up the stairs at a specified rate and for a specified time without loosing his/her balance. The weight is a 80lb weight vest on a revolving stairmill at a rate of one step every second for three minutes. I thought about wearing a backback with weights on it at the gym but I'm afraid the weight will rip the bag. Any suggestions? O and were not allowed to touch the rails.
