"If you want to get faster, if you want to increase your work output, you have to approach those two different sessions in the same way." "If you do want to get faster, if you do want to be able to run further for longer at faster paces, you need to kind of split up the focuses of each one of those training sessions and supplement them in throughout the week." "Racket sports with throwers, especially a lot of crossover there but as far as like the work capacity point definitely a lot easier to sort of program in or give to guys to when you give them like a competitive outlet." "Conditioning for court sports is miserable. If you put us indoors and you just give us lines that we have to go back and forth on for 200 times or whatever for an hour straight. That's the physical sport representation of the looney bin essentially." "The reactive component to pitching is completely unreactive in the sense that you start every play with pitching. You have 20 seconds in between throws and you're throwing to a stagnant target." "You need to verbalize it in order to give it less of an importance or a significance. I'm going to use the Y word."
