I've really enjoyed the moves (Z legs + legs extended forward) to release the hips and the thoracic spine. What a nice stretch! I haven't understood the purpose of placing the block under the leg for the seated spine twist. Is it to release the quads by pressing down the hamstrings? Thank you in advance for your answer.
Hi Lina ~ I believe the answer to your question is to simply release the hamstring if it was tight so someone could align their pelvis and spine more easily. Not everyone sits well with straight legs pressed down into the floor. Does that make sense?
