PLANK TO LIZARD 2
This is an advanced version of the Plank to Lizard above. If you want more of a quad stretch, once your foot is next to your hand, slowly lower your back knee toward the floor. If you still want an even deeper stretch, start to bring your ankle closer to your hips and take your opposite hand and reach back to grab your ankle. Take deep breaths and go through this very slowly to allow your muscles time to stretch and adapt.
