| Exercise Bike vs. other machines
Is this is a good cardio machine? I have heard that it makes womens hips larger??? Im sure its just a myth... Is there a better machine to use for cardio? I try and do 40-50 mintues of cardio a day... either running, elliptical, or bike... most of the time i break up the time between all 3... is this a good routine, or should i just focus on one over another?
