Want to release tension after a long day at your desk? Try Puppy Pose. It opens the chest and stretches the spine, neck and shoulders—perfect for counteracting bad posture and waking up the body (yep, it doubles as an awesome morning stretch). The best part? Anyone can do it! If you have sensitive knees, slip a bolster or blanket under them, and for a deeper stretch, try resting your hands on blocks. Check out the tips below to get the most out of this essential pose.
