The Fix: Lengthens the spine and opens up the chest.
How to Do It: Lie facedown on the floor with hands directly under shoulders, legs extended back on the floor. Tuck hips downward and squeeze your glutes. Press shoulders down and away from ears as you lift your hands up, using your chest muscles to rise toward the wall in front of you. Keeping your legs together, press the tops of feet into ground, lengthening your tailbone toward your heels.
Why It Works: “Overhead movements — pull-ups and ring rows in particular — benefit from doing Baby Cobra," says Karen Kelly, a yoga instructor at 908 CrossFit in New Jersey. “It trains you to keep your shoulders down and back while distributing the ‘curve’ evenly throughout your spine.”
