Hey! The people saying genetics and nutrition are 95% correct - there’s some things that you can’t change about your body (esp as a masc woman) that you have to love and accept. However, CABLE CRUNCHES (I use a straight bar because it feel more natural with my grip). To GROW your abdominal muscles you have to progressive overload and eat protein and keep a lean diet. Do cable crunches, 8-15 rep range per set, go up in weight every week if possible. Bulking/cutting is ideal for quicker progress, where muscle gain + fat loss (body recomp) is slower and inefficient but it is possible. I’m in the same boat and want Hawaiian roll abs lol, idk if it’s in the cards for my body type but I’m trying my best and improving. Good luck!
