I don't "feel a burn" at all, unless I do eally high reps, but I train heavy, so my reps are not that high. A feeling of burning is not a sign of growth stimulation. If it was, intense cardio would give you huge legs-and that doesn't happen. Shaping the muscle just isn't possible. I've never seen one top bodybuilder change the shape of his triceps-bigger-yes, more defined-yes, even fuller and more developed, but changed shape-nope. Franco Columbu did preacher curls for his lower biceps for years. Did he feel a burn there? maybe. Did he change the shape of his biceps-nope. It has to do with the inervation of the muscle. Check out Hatfield's work on contigous versus non-contigous innervation. Note- the pecs are an exception as there are two muscles there.
