What It Does This integrated core exercise builds strength and utilizes the full range of your core muscles, particularly the back.
How to Do It From your knees, lean forward until you come to rest on your forearms with palms in prayer position. Staying on your forearms, lift legs up into plank position, curling toes under, so that your body forms a straight line (also called elbow plank). Exhale and, hinging slightly at the hips, lift hips about six inches to form a triangle. Inhale and return to elbow plank. Repeat 10 times.
