Always Be Recovering
Recovery is a fickle bitch. Treat her nice and she'll be nice to you. But mistreat her and you will pay severely. Around the interwebs you'll hear expressions like, "There's no such thing as overtraining, only under-recovering." Sometimes less is more. I've certainly seen plenty of people overtrain and run themselves into the ground with overuse injuries, adrenal fatigue and metcon burnout. Were these folks under-recovering? Bitch, I don't know your life!
If you're training three to five days a week, which is an average range for most CrossFitters, your body is in a state of constant recovery. When you think about it that way, it makes your food choices that much more important. You really don't get a whole lot of leeway if you intend to optimize your recovery. Every single thing you put in your mouth-hole matters. Is that entire box of Samoas that you just inhaled helping your recovery process? Not so much. A 16-ounce rib eye with a huge side of mashed sweet potatoes and steamed broccoli smothered in pastured butter? Now we're talking.
You need to approach your training from the standpoint that you're always in a state of recovery. Injuries don't occur from overtraining, injuries occur from under-recovering. The foods you eat, supplements you take, the amount and quality of sleep, and time spent on mobility work all need to be accounted for on a daily to weekly basis in order to maximize recovery. A: Always. B: Be. R: Recovering. Always Be Recovering.
