Move 2: Push-Up and Pop-Ups
Begin in high plank, with your hands directly under your shoulders and legs extended.
(A) Lower into a push-up, then press back up to the starting position.
(B) Jump both of your feet forward so that they’re just behind your hands. Shift your weight forward and jump your feet back so you return to plank position. Repeat for 45 seconds, then rest for 15.
