It's difficult for someone to just give you a blanket reply that can accurately depict everything
you'd need to grow. Keep your workouts HARD, split 'em up so that you're getting plenty of rest in between training each of your bodyparts (oh yeah, don't neglect any), make sure you're macronutrients are in check (protein/carb/fat ratio is clean and balanced), and consume tons of protein. Those are some cardinal rules for anyone looking to see change, I'd say.
Most importantly though, don't get discouraged if you don't see results immediatately. Being that you're an ectomorph, you aren't going to have crazy gains like a mesomorph, right away (KEY: right away
). As long as you're eating right, resting plenty, and training with high intensity though, you'll see improvements in time. Actually, you're lucky. Since you have such a small frame, and joints, any muscle you pack on will contribute to a potentially sick physique; tons of muscle separation! Lucky you
Keep up the training, 2cool, it'll pay off.
