I actually find both of these very true. The use of parameters and not being stuck on 3x3 or 5x5 or what have you.
I have very flexible parameters really and they are more of the training WEEK variety, Just get in this stuff this week and in general lift heavy. some days that means I do a ton of doubles some days I will go high rep just to torture myself. a lot in the middle somewhere or pyramiding up/down.
Same with the days and what I do that day. This boils down to the time I have and also just what I FEEL like doing. a few months ago it was 6-7 days a week. then recently I was doing three full body sessions due to time issues. Now Im doing two upper two lower for three weeks now and considering going back to the 6-7 days. Just feels like what I may want to do now.
It for sure is about getting a vocab and what works for you. I mean I can take peices of EDT, peices of frequecny, 10x3, all of the crap over the years and fit it into MY lifting as I see fit and feel it will be effective.
But like Pro.X kind of elludes to (I think) a lot of poeple may not have the time under the iron yet to really train instinctively. Know what works takes time and you have to actually DO the stuff not once but give it a fair run weeks months and see what the hell it does. Heck I am and always will be learning and trying new stuff. Stuff that I may or may not add in on a regular basis. Thats what its all about.
Ok I think that may make some since. Maybe,
