If the same objective, the same training goal, is just muscle tissue growth—and we're not talking about maximal strength or any of those type of parameters, we're just talking about growing muscle—if there's an athlete A, and they do 6 sets of 10 with 2 minutes rest, and there's athlete B that does 6 sets of 10 with 3 minutes rest, athlete A will likely see the highest muscle gains, muscle hypertrophy gains.

Everybody in the UFC trains hard ... The best athletes, the true elite levels, are the ones that can do it again and again and again on a daily basis and sustain a technical output for skill development.

Testosterone is really stimulated by an intensity factor and also a volume factor. Now, growth hormone is a little bit different; that's largely driven by an intensity factor alone.

If you look at true skill development, it is about rehearsal of accurate movement, accurate movement mechanics ... As soon as that becomes impacted by fatigue or inaccurate movement, you're now losing the motor learning; you're losing the accuracy of the skill.

We would never ... I never say never ... We rarely advocate a high-performance athlete in a high-intensity intermittent sport, like MMA, being totally ketogenic.
