Hi, I’m 16 years old about 130 pounds, 5’5″ , small for my age, but already somewhat toned, if I flex there is much muscle definition, but not a 6 pack more like a 4 pack.. If I don’t flex I just have a flat stomach, I have little fat and some muscle.. I want a nice toned 6 pack, and nice bi’s and tri’s, I also need bigger pec muscles because my upper body is very small.
Can somebody please give me a good workout routine that will help me too achieve this? In steps, and reps, and days, etc..
