Start with a standard high plank. Slowly bring your right knee toward the outside of your right elbow. You’ll be tempted to look back to see how close your knee is—don’t do it! It will make you round your shoulders and drop your hips. Just get it as close as you can without losing your form. Be sure to have your hands stacked underneath of your shoulders and keep that core engaged the entire time! Repeat on the other side. Perform 20 total reps alternating legs (10 on each side) on each side and complete 2-3 sets. Enjoy!
