Hi Cluelessparent... I've followed your saga and I hope things are better and I
wish I had a parent like you

I hate to disagree since you were so kind but the light vs heavy
myth needs to die 🙂 I believe that it has been proven that
lighter weights do not affect whether you add bulk or not. Testosterone, genetics
and it's affect on HGH is the determining factor in muscle bulk. That is not to
say you cannot be strong, but you will have slim toned muscles, not
large bulky muscles.
Most GG's simply cannot "bulk up" regardless of the amounts of
weight they lift. Women that you see that are body builders either
have the top 1% of the genetics or are using steroids. No woman
should fear lifting heavy weights... you simply cannot build big muscle's
unless you are in that rare 1% genetically.
Due to mostly genetics as a male I was never able to "bulk up" either through training even though I was
lifting the heaviest weights possible and following a strict training/diet regime and was ridiculously strong. I
had friends that trained with me daily that started at the same place I did and grew to enormous proportions
following the same intensity, diet, training regime I did. I simply did not have the genetics for it.... which I'm
very thankful for now

I did bulk up in my 30's but that was just due to visceral fat not muscle from less exercise more
calories and age
