Staircase to Hell

This workout takes 20 minutes. Do as many rounds as you can in that time frame:

1 stair run
10 Wall Ball Throws
1 stair run
10 Jumping Lunges
1 stair run
10 Box/Bench Jumps
1 stair run
10 Deadlift, RDL, or Sumo Deadlift
1 stair run

Try for 4 or 5 rounds. This means you will have to run up and down the stairs super fast. Good luck breathing.
