When box jumps are in a workout, there’s always that chance of miscalculation. I’ve definitely been a victim of the unforgiving edge of a 30 inch box. BUT! I didn’t let that stop me from trying again. After feeling the pain, it can definitely psych you out from trying again. Just remember, you’ve jumped up there before. As long as you focus and give your best effort on every rep, you’ll be able to keep on jumping. Don’t give up and believe in yourself, you can do it!
