This philosophy is at the heart of how I look at sport, and how I coach myself and other athletes (only a few). What I coach for and care about is performance. Clients pay half up front, and half when they reach a specific performance goal. If they don't reach it they don't pay. It's all about performance, all about real-world results, full stop. "Fitness" is relevant to that goal, but the vast majority of the people I work with need nothing more than dedicated and semi-organized sorts-specific training to develop the fitness required to perform. If they need a base level of human function then I'll pull from other areas to get that, or send the individual to someone else first.
The real reason I train using non sports-specific protocols (Crossfit, Yoga, Gymnastics, old-time strength stuff, etc) is that I like being a functional human. Deadlifts help my back feel better. Squats help my knees not hurt. I like the way I feel if I hit the WOD regularly. I like to be able to sprint (although I would be mocked at any serious track in the world). It's good. And within that "human" training performance still counts. Better form. Better range of motion. More. Faster. But deadlifting will not help me redpoint my project as much as spending the same amount of time climbing will. So I'l cycle general training and skill training. One for sport performance, one for life performance, both important to me from a performance standpoint at different times in my year.
So there, it's resolved enough for me. Do sports-specific stuff to perform better at sports, especially the mountain sports I do and know well. But also enjoy having a functional body, and find a protocol that works for that. Have performance goals, and be honest about what they are. Be savage like a chain saw in examining the successes or failures of reaching those goals. Learn, think, evolve, try not to be a dogmatic ass, grow as an athlete and human. Train, perform, give 'er, but listen to that old Norwegian coach in the back of your head. There's honesty in saying, "I train 'cause I like the way I feel, yeah!" I can tell when my wife has done her 7:00 a.m. WOD 'cause she's happier. And that's worthwhile.
Intervals rock. I just want to say that. They hurt, they're annoying, but man do they get results. More on this later, just something I'm excited about right now. Intervals...
