The popular yoga posture, Downward Facing Dog is the perfect combination of strength building and flexibility. Try this modified version when you are somewhere that being on your hands and knees is not an option. Find a desk or sturdy table. Place both hands down and use your thumbs as anchors on the edge. The hands are shoulder distance apart. Now walk your feet back until your body is straight and your hips are stacked over your knees. Deeply breathe in and lean forward. Breath out and sink your shoulders and head toward the floor. Relax, dont push as this puts undue pressure on the joints. Walk the feet back until you feel a good stretch. Lift at your belly and breathe deeply for 5-10 breaths. Exhale as you walk your feet forward, inhale and stretch to the sky to complete this pose. Namaste.
