Plank to Down Dog With Ankle Reach Start resting on all fours. With your palms flat, raise up off your knees onto your toes. Keep your hands directly below your shoulders. Press back into a down dog or pike position. Reach your right hand back toward your left ankle, coming as close to touching it as you can. Return to high plank position to complete one rep. Complete for a total of five reps on each side. Image Source: POPSUGAR Photography / Louisa Larson
