Same thing happens to me, I do blame myself for not exercising more and being more flexible. Once this happens, just move your hands above your head and lock fingers, you can continue float, your neck will not hurt you. When I am doing longer 90 mins sessions and after some time, your neck starts hurting and this prevents neck hurting and I can have my full session. If I did yoga, I wouldn't have this problem, but I am wimpy and lazy.
