Upward facing dog

Lie face down on the floor with your legs extended behind you. Place your hands on the floor next to your lower ribs, fingers pointing forward. Press your hands firmly into the floor and straighten your arms, lifting your torso and thighs off the ground. Roll your shoulders back and down, opening your chest and lifting your gaze towards the ceiling. Hold this position for a few breaths, then slowly lower your body back down to the starting position. Repeat for the desired number of repetitions.
