This series will work up a serious burn in that core! Grab your med ball and follow along.
1 round = 5 crunches and 5 russian twists with one leg elevated + 5 of each with the other leg elevated + 5 of each with both legs elevated.
Notes on form:
- Lock out the knee of your elevated leg by squeezing your quad.
- Stabilize your lower back by squeezing the glutes tight.
- Constantly pull shoulders down away from ears.
- For russian twists, keep elbows wide and keep med ball resting against center of chest.
