I hear that about gaining weight. If I were not actively trying to drop weight by cutting calories I would be getting heavier. I have to keep telling myself that muscle weight is worth it. Think about it wouldn't you rather be a stone heavier and able to use more watts on a climb and in the flats or be lighter on hills and get burned on flats because you don't have the muscle you need to generate power. If I remember right you were into ITT here it is better to be a little heavier and have greater power, except if the TT is uphill.
