The seated twist also stretches your glutes and feels great on the spine after a run too.
Begin seated on your mat with your legs extended straight out in front of you.
Bend your right knee and place your right heel as close to your left sit bone as you can.
Reach your right arm behind you, and plant your palm or fingertips on the floor. Place your left hand or elbow on your right knee or thigh, and gently pull your knee to the left until you feel the stretch in your glutes.
Hold for 20 to 30 seconds, then repeat on left side.
