- Start in the extended arms plank position. Keep your head neutral and back straight.
- As you exhale, turn your right knee outward and bring it toward your right elbow.
- Return to the plank and repeat on the other side.
The next level of this exercise is doing it in a low plank position. Make sure your elbows are directly under the shoulders and your core is nice and tight. Continue alternating sides and exhale each time you bring the knee to your elbow.
