Start in a forearm plank position with your elbows directly under your shoulders and your body forming a straight line from head to heels. Engage your core and keep your neck neutral.

Press into your palms and extend your elbows, lifting your body into a high plank position. Keep your movements controlled and avoid letting your hips sag or rise.

Slowly lower back down to the forearm plank position by bending your elbows. Repeat the extension and lowering movements for the desired number of reps.
