5 – Lots of Days Off Are a Luxury You Can't Afford
The conventional thinking is that old bastards need to take more time off sitting at home in an easy chair eating protein-laced porridge until the poor old coots can gather the strength to get up and shuffle-walk to the gym.
It's true in one way, but false in another. Sure, older guys need to focus on recovery more than younger guys, but they often convince themselves to take off more time than necessary. They end up taking off because the mass of sweaty, training humanity says they're supposed to, rather than taking time off because they need to. The incessant recovery drumbeat messes with their heads.
There's one thing that should tell you when to legitimately take a day off, and that's your training log. If it tells you that on Tuesday you failed to exceed, or at the very least, meet the previous workout's numbers, it's time to take a day off.
If not, get thee to the gym, just as you have since time immemorial.
