I already have pretty small boobs, im a 34B ..
I've been recently getting much better in my upper and core strength.
I am able to do full body pushups and i have lost a lot of fat
Im starting to realize that my boobs are also shrinking and it is really upsetting me.
Should I stop doing push ups? Eat more healthy fats to gain boob fat? Someone give me advice please.
The best way to reduce breast size naturally would be to lose weight. I don't know your weight and am not asking but breasts consist of fat tissue just like other parts of your body. Doing pushup's will certainly strengthen your muscles however, I would not recommend pushups to reduce size. They would be great to do if your goal is to get into better shape, strengthening your arms, core and chest muscles as well as some others.
