1. Stair Climb
One of the CPAT events is the stair climb. Performance Health recommends building your endurance by training on stairs. Instead of climbing up and down multiple flights of stairs, start small.
Focus first on one step. Step up on one step with both feet and then down. Repeat this action 24 times in one minute, and keep this up for five minutes. You can add to the difficulty of this exercise by putting on a 25 lb vest. The next level of difficulty is doing this exercise while holding a 10-15 lb dumbbell in each hand.
