I`d hit a plateau on Back days. Gee, no surprise after decades of doing this stuff (no, I won`t accept that my age factors in

) but it still bugged me. I don`t really expect any significant growth, but still...
I was getting good and sore, so...hmmm, what could be suboptimal? I figured it must be recovery-related, so I decided to take my own usual advice and blamed overtraining, decided to rest longer.
Dialed back Back Day a little (I usually do ~8 sets, lots of areas to hit from lots of angles), and waited 15 days (did work Bis a little in the meantime since little muscles like those oughta recover pretty fast). That`s just one extra recovery day, but it made a difference! I was able to add weight/reps/both to every set while maintaining good form. I dunno if I`m actually gonna change my workout schedule since my usual "which days I do what" fits into my life so well, but it did reinforce the importance of recovery. Guess I really oughta do fewer sets while still hitting everything, or maybe not carry the Drop Sets on so long, or something..
Same ol` same ol`..
-Train hard enough to potentiate adaptation (and/but no more)
-Eat enough of the right stuff to fuel both workouts and adaptation (and/but...)
-Recover sufficiently for adaptation to occur
-Train again before decompensation occurs
Do those and, unless you`ve really hit your genetic potential, you`ll make some form of progress.
But Back Days really do go on forever; all those muscle groups in the back, then Bis, then Rear Delts, and then usually Core...that`s one very long workout, at least for me (I still rest a *LONG* time between most sets and I don`t mean just 3-5 minutes).
