This right here is an example of where most people will fail. Your on a good routine now probably making steady progress (if your not then you need to make a thread showing exactly what your doing, warm ups, diet, how long you've been doing it, since you should be progressing) but feel like theres more you need to do to take it to the next level. So you'll jump on some other crazy program and end up stalling out.
Channel that energy of wanting to go hardcore into your diet instead. That energy will then show itself in the form of not missing a single meal, measuring food to be exact, eating at the times your supposed to eat, recording down your food for the day, having meals prepared ahead of time, getting all water and supps down, doing the samething everyday so by the end of the week you know what changes to make. Do this and you'll be doing yourself a favor.
