We seem to get a lot of questions about getting stronger and maintaining weight. Before you ask that question, go and look in the mirror. Are you filled out yet? Should you even be asking that question? I bring this up because the standard answer here on this forum is 'eat clean lift heavy.' I'd like to remind everyone that your body is intended to be a certain way, and if you're too small and weak to begin with, lifting low reps and maintaining your weight won't help performance. Thus, lifting low reps and eating little will mean you'll be stuck being weak. Generally, getting the GPP to lift heavy involves hypertrophy. If you lift heavy without the proper GPP, you're asking for injury and no progress.
