My L3 gets tight and it makes it difficult to sit. I trainned my dog to go over the area but he's only 60lbs. Ideally someone, a woman, ideally, 100-120lbs can balance using a wall and go over my back for 1hour. I live in Pacifica. I've got my own house. I'm professional and my home is clean and welcoming. I'm 6'0 and would gladly exchange information and cost.
