anyone know any exercises I can do for my arms and thighs while im pregnant? besides squats please. i tried doing them but it started to hurt my back, it doesn't when I'm not pregnant but since I am it hurts lol. I feel so gross cuz I stopped working out since I've been pregnant but I don't wanna over do it or anything.
