I remember back in my elite age-group (whatever that means) triathlon phase people would say things like, "Race weight is the weight at which you get a stress fracture plus one pound." You know what's dumb? That.
(A short thread)
Guess what? This is a god-awful aphorism. It's terrible for your performance; terrible for your physical health; and terrible for your mental health.
How about stop training 30 hours a week and start sleeping more. Low-T isn't your illness. The lifestyle is.
Give me a break! Unless you are making a living racing, this isn't for your sponsors; it's for your ego! Again: a very unhealthy pattern to get into.
Rest when you're tired.
Don't take yourself too seriously. And if you're good enough to, get a coach—not a weekend certification one, but a real one—who can help you ride the razor's edge without being reckless.
