Maybe I should clarify a little. My TM is already lower than it probably should be but that is because I am using 531 to supplement my primary sport training which happens 6 days a week 15+ hours. No that isn't an exaggeration. It has worked for me because of the start light mentality, low volume, minimum time required in the weight room, and the fact that I can space it over 4 days... which allows me to step out of the weight room and into my regular training session without being gassed.
So clearly recovery is critical in my situation and to date I have managed well enough that I rarely miss lifts. When I do miss lifts it is consistently when I step off an airplane into the weight room or if my recovery wasn't adequate.
I have lowered my TM's in the past when I see consistent fails outside of those two parameters I indicated with much success.
My confusion is about the one off bad sessions I may have. In those sessions, I rather still do "something" with the time, if I fail in one set of a lift. Or is that just not the way it is designed. ie: you miss rep 3 in set 2 week 3... so pack up and go home. Lower TM again etc.
Thanks, everyone. I've been lurking on this forum for some time now and it really is fantastic.
