Exercise is known to increase testosterone production (even in natal females) which helps to build muscle. Truly, if you want the biggest breasts possible sacrificing all else to the boobie-God, then eat more pies and gain weight. Breast are composed of subcutaneous fat and glandular tissue. The glandular tissue makes up only a small part of the whole breast, with the majority being fat. The fatter you are, the bigger your boobs. Look around and you will see this is true for morbidly obese males as well as natal females.

All other things being equal, I would keep exercising as you have been, and keep your weight in a healthy range for you height and body type. Give em time, they will grow. Mine sure have, and I try to exercise 3 to 5 X/week.
