This back stretcher is a game changer. My back is always stiff, especially my lower back. I’ve been using this 3 times a day for 2 days and already notice a huge difference. I’m only using the 1st setting and that gives me plenty of stretch. It feels absolutely awesome! It mentions on the instructions that this can be used for side stretching also, I’ve tried it once and it feels great, but I’m going to get my back in shape before I move on. There’s a 200lb weight limit, which would be quite a lot since you aren’t putting your full weight on it, only your back so there’s some leeway there. I honestly have no complaints about this back stretcher!
