You can do a simple Mountain Pose anywhere and anytime, said yogi Anita Perri. It's simple "but so beneficial for the mind and body," providing a lengthening and posture-improving stretch in your feet, legs, and spine.
Stand with your feet hip-width apart and your hands by your sides or pressed together in front of your chest as pictured.
Elongate through your torso, engageing your core and staying strong from your thighs. Imagine that you're lengthening your whole body through the crown of your head.
