Age counts too, I think, with regards to recovery.
Being over 40..... just
Bryan once advised me to try reducing the heavier workouts, ie; the 5s and negatives, to twice a week - so my current set up would be 3 X week for 15s and 10s, and 2 X week for 5s (still 6 workouts, so lasting three weeks rather than two) and negatives.
I am, courtesy of O&G's very valuable advice, currently incorporating myo reps too now.
Everybody has different tolerance thresholds, not to mention other commitments that get in the way.
In my mid 30's, I was lucky enough to have had the opportunity to train twice a day (whole body each session) - 6am and 4pm - every Mon/Wed/Fri, and - even taking into account that I was at my natural physical peak then, I still made my best ever progress (I hit 290lb at around 20% bf)
Sadly of course, it's all been downhill ever since then...
