This move takes the power of a plank and literally turns it on its side. Start with a knee down and then progress to both legs being straight as you work up to it.
- Start in high plank position with your hands directly under your shoulders, fingers pointing forward.
- Drop your left knee to the ground, and rotate your hips counter clockwise until your right hip is directly over your left hip (perpendicular to the ground).
- Lift your right arm straight, making sure that your shoulders are stacked in a direct line, your right shoulder above your left. You should look like a T angled on its side.
- Keep your right leg extended over your bent left leg and lift your hips by squeezing your glutes to keep your side body in a straight line from your shoulders to the end of your straight leg.
- Slowly rotate your right arm back to the ground as you lift the left knee to return to full plank.
- Repeat the process on the other side: drop the right knee, and rotate your hips clockwise as your left arm opens to stack the left shoulder over the right.
- The left leg stays straight over the bent right knee. Squeeze those glutes.
- Do three sets of 10 (one rep equals rolling to both sides).
