It doesn't matter what you do as the principles are the same - what always works for me is training for PR's, not being a fool with the TM and never training with morons. As long as you eat for strength, maintain basic aerobic function and mobility, the basic principles of pushing for PRs, start too light, progress slow and focusing on the main lifts ALWAYS win.
How many days/week or whatever is not terribly necessary to the goal. I have trained 7 days/week and 2 days/week and as long as the principles are never compromised, it always works. The trick is never compromising, not being swayed by the Paleo Majority and being 100% devoted to your Training Ideas.
