Runners are familiar with the relaxing runner's lunge stretch, and although this looks similar, I assure you this pose is all about strengthening your thighs. As a bonus you'll also get a nice stretch in the front of your hips.
- Turn your torso to the left 180 degrees, planting your right hand back into Down Dog position. Straighten your right leg into the air, coming back into Three-Legged Dog position. Step your right foot forward between your hands, as if coming into Warrior 1. Lower your torso and reach your right arm underneath your bent right knee. Interlace both hands in front of your right ankle. Keep all the weight in your legs, resisting the urge to lean into your hands. If this is too intense for your thigh muscle to hold (it's a killer move!), then rest one or both hands on the floor.
- Breathe deeply in this low lunge for five breaths.
