By nature I am an endomorph, it sucks! currently I am 178lbs pretty muscular, but quite a bit of bf. What I want to do is change my body to be more of a mesomorphic type, but I am having a hell of a time fighting my genetics, people say it takes days of breaking your diet to see a change in your weight, for me, its almost immediate....is it in my genetics to gain fat easier? To give you an idea of my size, I am 5'7 1/2", 178lbs, squat 415lbs for 4 reps, flat db press 120lbs for 6 reps, don't do deadlift (injury related), about 15" arms (proportionally the smallest muscle group are my biceps) most of the size comes from triceps. I guess you would say I am an endo mesomorph, but what I would like to be just an mesomorph....is this possible? I don't mind losing strength, but I would like to keep as much LBM as possible. I just want to know if it's possible to change your genetics by nutrition and excercise.
