Decided to try this, knowing I can't do tree without a wall (no arches, no balance) I needed the strap with the forward bends, arms over, and enjoyed the shoulder stretching, as mine are extremely tight. I LOVE the spinal wave, and will take this with me as a daily practice, the oscillating is so soothing. Middle section was a bit too fast for me, not a fluid surfer, I guess. Love the stretching at the end, so there are a few movements I will take from this practice. Grateful for the challenge.
