Both true and false. Women can get large bulky muscles without taking any "supplements" I am an example. When I was in top shape , my chest was 43" and B cups, by upper arms would not fit into womens t-shirts. But hey I could bench press 280lbs ( now only 230lbs) . And no I was not trying to body build but rather going for strenght. I did push ups everyday , at least 100. It is better if you do every second day but in the military not much choice when doing morning PT.
Now my wrists hurt too much to do regularly but I did try
I got to 83 before my right wrist gave out. Now my arms feel rubbery. Fun.
I'm not bulking up but I have definition that I never had before. The only negative is that my boobs seem smaller
