Push-Up Burpees
From standing, bend down and place hands on the floor. Then jump feet back so your body is in a plank position. Do one push-up, then immediately jump feet forward toward hands and return to standing. Do 10 reps.
Perfect Your Form: Don’t arch your back when you jump back into plank.
Dial It Down: Do push-up from knees or skip it.
Amp It Up: After returning to standing, do a power jump into the air.

Mountain Climbers
Start in plank. Bring one knee, then the other, in toward your chest, switching legs in mid-air so that only one foot touches the floor at a time. Repeat for 30 to 60 seconds.
Perfect Your Form: Keep shoulders positioned directly above your hands.
Dial It Down: Tap your toes on the ground when bringing knee into chest.
Amp It Up: Super-boost this exercise by doing as many mountain climbers as you can in 30 seconds.

Squat Jumps
Standing with your feet hip-width apart, lower into a deep squat with your arms bent in front of your face. As soon as your thighs are parallel to the ground, jump up in the air. Do 10 reps.
Perfect Your Form: Make sure your knees don’t cave in or rotate out.
Dial It Down: Perform the squat without the jump.
Amp It Up: Put a box or step in front of you. As you stand up from the squat, jump onto it.
