You’ve got your jumping jacks dialed, and you know how to do a plank . . . but have you tried plank jacks?
This core-plus-cardio move will get you sweating, raise your heart rate, warm your arms, and work your legs. Make sure you keep your spine neutral! Here’s how you do it:
- Begin in plank position, with your shoulders over your wrists, your body in one straight line, and your feet together.
- Like the motion of a jumping jack, jump your legs wide and then back together. Jump as quickly as you want, but keep your pelvis steady and don’t let your booty rise toward the ceiling.
- Do a total of 30 jumping jacks, which counts as one set. Then complete two more sets.
