Whenever I do butterfly stretches I do them for quite a long time, but whenever I stop It takes me a while to move my legs out the position because they are stiff and really hurt. It makes my feet (and sometimes legs) numb. Yesterday night I was in agony with my legs.
However, I mainly do them lying in bed (Well, I don't actually think it's a proper butterfly stretch - I just put my legs in the frog leg style position and lie there for as long as I can. I feel like it still works the same as its tender at my inner thighs when I press them, which is the same for when I do them normally).
Am I doing them right? Should I stop? Will lying down with them give me long term/any health problems?
