Master the Box Jump
Valid Fear: You’ll ding your shins on the edge of that 20-inch-high plyo box as you try to hop atop it. You can gt over this hurdle by coming at it from a different angle – literally. Stand facing the corner of the box so your legs have more clearance on either side then they would facing the straight edge. Build your confidence by sticking some landings and stepping down, then do those box jumps head on.
Give this circuit a try: Do 5 push-ups, 10 box jumps, and 15 squats, and repeat for as many rounds as possible in 10 minutes.
