You can start off sitting or standing.
Slowly and with ease, take your right ear toward your right shoulder. It’s natural for your left shoulder to lift as you do this. If that happens, ease your head back toward center until you can relax your left shoulder back down.
Lift your right hand up and over your head, resting your hand on your left cheekbone. Do not pull on your head now, though. Simply rest your hand there for just slightly more pressure. This very gently stretches your upper trapezius.
Breathe as you sit here for at least 30 seconds.
Gently release this side, and then ease your left ear toward your left shoulder and complete the stretch on the other side, breathing deeply through it.
