Training for the 'centenarian athlete' phenotype requires prioritizing injury prevention over peak performance.

“one of the biggest trade-offs you have to make is optimizing against getting injured because the compounding effect of training is so strong that it's rivaled only by the compounding effect of not training in other words correct yeah you know exactly what I'm saying but for the listener um you will lose it way faster than you will gain it and therefore you could argue rule number one of what I'm proposing is you can't ever stop training to to have an injury that Sidelines you for three months is an unacceptable risk even if the concessions you make for that cost you some Peak Performance okay”

“injury must be avoided at all cost because injury means time to decondition and the older we get the more uh problematic that gets”

“So that's why um as far as I'm concerned once you reach my age uh in your 50s rule number one of training is don't get injured.”
