Start in plank position with your forearms on the floor, Brace your abs in tight so your body forms a straight line from head to toe (imagine you have a tight corset around your waist during this entire workout). Next, pike your hips up higher than your shoulders as you lift your right foot off the floor and tap it in by your left. Step your right foot back to your start position and lower your hips back to plank (don’t allow them to sag below your shoulders).
