Hi, I am new to this site, and am looking for some advice. (I have been registered for a while, but have only started to ttc this month). Anyway, I feel I need to tone up a little, and I wanted to know the best excercise that is safe when ttc. I guess swimming looks really good, but I really can't find time to do it. I have just bought a bike, will that be too strenous if I were to get pregnant soon?
