If you're looking for a way to burn calories while toning your upper body, core, and calves, have I got the exercise for you. This is a variation of plank that you can do anywhere, and may also be called mountain climbers.
"Back Back Back," by Ani Difranco
If you'd like more detailed instructions,
- Begin in plank position (top of a push-up), with your shoulders over your wrists and your body in one straight line. Engage your abs to protect your lower back, and step your feet together. Spread your fingers wide to take pressure out of your wrists.
- Bend your right knee and draw it forward as close to your chest as possible.
- Then simultaneously and quickly step your right foot back and bend your left knee into your chest. Keep alternating so that you're essentially running in place. Move as fast as you want, making sure to keep your abs pulled in and your shoulders over your wrists.
- Complete 30 steps (15 on each side). This counts as one set. Complete five sets, either taking a break in between by doing Child's pose, or do all five sets in a row.
