Circuit 1, Exercise 3: 2 Jumping Jacks, 2 Burpees Start with two jumping jacks. Jump off the balls of your feet as you hop your legs out, then back in, with softly bent knees. Next, do two burpees. Bend at both your hips and knees, placing your hands on the floor in front of your feet. Jump both of your feet backward into a plank position so your legs are completely extended behind you. Do a push-up, lowering your chest to the mat and returning to a plank position. Jump both of your feet toward the top of your mat behind your wrists, landing in a squat. Jump up into the air, extending your arms above your head, before landing with control. This counts as one rep. Keep doing two jumping jacks and two burpees for 30 seconds.
