I probably have low T and shit genetics but how realistic are those 1 year transformations. It seems that they gain significant amount of muscle despite doing fuck all. I've been coping with calisthenics and my physique barely changed. Sure, I slightly developed lats and triceps but that's about it but I went from 0 pull ups to 15 so it means that I'm doing something right. Question is, am not training normally or I'm just delusional about one's progress.
