This is a very n00b type question sorry. I have been on T-Nation for quite some time reading forums and articles but have not ever replied to any posts. I thought I would ask the T-Nation members as I trust your knowledge.
My question is this, I am 17 and I'm not very buff at all. I'm 45Kg, BMI 16, 162cm, 5Ft 5inches(I think).
When a first started working out, about a year ago, I read "BodySculptingBibleForMen" it said for teenagers you should keep reps easily at 20 or above.
Not that long ago I got "Scrawny to Brawny" its mainly covers people like me (Ectomorph) and they recommended that a stereotypical ectomorph should keep reps short and sweet, 12. They said the reps need to be intense.
Now when I work out, if I do sets with 12reps I dont have to push myself as much and dont feel the same DOMS afterwards. With sets of 20reps I get really good (bad, however you look at it)intense DOMS afterwards. Is it true that if I do low reps (12), I will put extra strain on my growth plates and not get my full growth potential. Being 162cm I aint tall and dont want to stunt my growth but doing the wrong amounts of reps for myself.
What do I do?
