10-Minute Cardio For Abs
Carve Your Core With 10 Minutes of Cardio
This move is essentially running in a plank position and really works your abs and arms and gets your heart rate up.
- Start in a traditional plank, and with your core engaged, bring your right knee forward under your chest. Return to your basic plank. Switch legs, bringing the left knee forward.
- Keep switching legs, and begin to pick up the pace until it feels a little like running in place in a plank position.
- Continue "running" in your plank for 30 seconds.
