Strap-assisted revolved spinal twist

Technique

Sitting with legs extended, bend the right knee and bring the right heel back toward the hip bone.
Keep about a palm’s width between the foot and the opposite thigh.
Lay a strap across the left thigh.
With the right hand on the floor behind you to help keep the spine tall, twist to the right and bring the left upper elbow across to the outside edge of the right leg, and then internally rotate that upper arm to wrap around the bent leg and grab the strap.
Reach the right arm back to grab the other end of the strap.
Gaze over the right shoulder and take 5 breaths.
Unfold and repeat on the other side.

Keep the spine tall as you twist. Support for this action comes from the deep core and psoas major muscles. Keep the extended leg grounded and the weight forward.
Avoid leaning backward or collapsing in the lower back as you twist.
It is common for the bent leg hip to lift off the ground in this posture. That is ok and actually quite normal.
