i gotta tell you guys, i don't care what people say about "it's volume, not intensity that determines overtraining". whoever came up with that must've had the pain tolerance of a little b*tch or thought "volume" meant 20+ sets for one bodypart.
over the years, i experimented with all kinds of routines, methods, etc. one thing i've learned, at least for me personally, is that while on a cycle, the cycle helps to regenerate my muscle tissue, but does very little to nothing for my CNS. on that note, in the past when i've tried to increase my intensity during cycles, it's always ended up the same way. i'd overtrain. the most effective approach for me when going on cycles has always been to slightly increase my volume (more sets for each bodypart).
now, this is coming from someone who would push it to failure on almost every single set i'd do, after my warm-up of course, so maybe with some of you it would be different. but i've learned personally that if you're pushing yourself to your absolute limits on every single set, even without large amounts of volume, you will overtrain and burnout your CNS.
the best results i've experienced while on cycles is when i've increased my sets by anywhere from 2-4 sets per bodypart and kept the intensity about the same. i push most sets just 1 rep short of failure or stop immediately as i start to fail and only push through failure (or at least try to) on the last set of each exercise i do.
i'd like to hear other peoples opinions on this and see if maybe this whole "volume vs. intensity" thing might not be all that it was hyped up to be.
