Jumping Jack Push Ups
As you lower your body, jump your legs out wide (keeping body in straight plank position), and as you push your body back up, jump legs back together.
Use this 45-second interval to practice at whatever level of inversions you can. Maybe that’s crow pose; maybe it’s walking on your hands across the living room floor. Because I’m awful at handstands right now, I’m most comfortable crawling backwards up a wall while walking in my hands and then holding the position there. The next step will be facing the wall, putting my hands on the ground and kicking my legs up against it.
