1. Tadasana a.k.a “Mountain Pose”
Runners are notorious for poor posture (forward-rolling shoulders and head). Tadasana is the foundation of proper alignment both on and off the mat. Plus, better posture leads to more efficient breathing when you run.
Start with your feet hip distance apart. Roll your shoulders up, back and down so the scapula rest flat against your back. Float your head slightly up and back to rest atop your spine. As you stand and breathe deeply, imagine your torso is bright and buoyant. Perhaps even close your eyes. With each exhale, let your body ground. On each inhale feel your spine lift.
