Logan and I were just talking about this.
Sports science, like all science, is an evolving thing.
That being said, anexoric 20 year old, or a fat and pudgey, 25 year old trainer are hard to take advice from, especially if you're coming from the perspective of someone who has more than 3 decades of experience. It can be difficult to have confidence in an 18 year old who is under-weight telling some fat person how to do a weight loss program. They simply do not have enough hours on the planet to give sound advice in many instances. On the other hand, a national champion coach may be "out of it", and still have an intricate understanding of "the game", but, with a basis in older technology, and older science. You have to decide for yourself what you want to go with, and really dig into the science.
I have a friend with a degree in sports science, though, and with some things, his advice is sound. However, I have another friend with a degree in nutrition and the stuff he does is beyond stupid.
I have another friend who is a competitive bodybuilder, and starves in his contest diet. That's how his old-timer coach taught him. He came to me, and I got him eating, and got him dried out, and got him a 3'rd place The Europa Super Show. Had he carbed up the way I asked him to, he likely would have placed higher. (I bring my calories UP, when I'm leaning out. It's all science.)
Folks want an easy pill; a catch-all solution; they often don't want the truth about their idols, etc. They don't want to believe that folks that they idolize are creations of smart training, good genetcis, and really good sports science, implmenting the latest technologies.
We were just talking, minutes ago, about how folks would rather take some junk from the nutrition store, than take something that's real, natural and that WORKS. You can't tell them (the person asking the question) anything, a lot of times.
Folks are NOT logical, nor truthful, as anyone who has been around a while can tell you.
Other folks, are beyond lazy, and never do a thing for themselves...research...study...workouts...etc.
There's a bunch of just plain garbage that floats around about how to get big, lean, fit, and so on. We were talking last night about how some of the things posted here are so far from being correct as to beyond laughable (I'm talking the forumns, and not the articles).
I'm a firm believer in applying good science to good health, and, I'm proof positive that it works.
My fourth biggest frustation is those who lie blatantly to young folks about why they look like they do.
My third biggest frustration is folks pushing junk that doesn't work, and they know nothing about, and that is clearing unnatural. There's so much crap floating around in nutrition stores that it's amazing.
My second biggest frustration is those who are completely clueless, ignore quality science, and go with hype and marketing.
My biggest frustation, however, is the haters.....those who suck at it; won't change their plan to a winning one, and lash out in jealousy / projection.
Those of us who are life-long, high-level, advanced athletes, get there via not just one method..but several:.science...genes...hard work...smart training.
I think I'm more inclined to listen to someone with a track record, and someone who lives the life.
We do it because it makes us feel good. The haters miss that point completely. Whether you're a top-shape bodybuilders, or a competitive marathon runner, you understand the discipline, and hard work of going there. It also makes you feel good. It's called hitting "the zone." Most neophytes have no clue about the zone. Some will never know it.
My first trainer, Sagi Kalev, was awesome. Sagi is the most photographed sports / fitness model in the world. Sagi has been on the cover of Muscle and Fitness, and Muscle Mag more than any man alive. He also is a great guy, and expert at what he does. ( http://www.sagikalev.com) I learned more than one trick from Sagi, and we are good friends today. At 38, Sagi shows than you CAN do it well into middle age, and at 48, I show you that you that you don't have to be a fat, out-of-shape, med-gobbling, guy, but, you can continue to improve. The proof is in the science. Sagi and I lifted together for about four months (he offered to train me for free if I couldn't afford it...realizing my potential...and...being the nice guy he is...)
I'd pick someone with a track record that's not pushing nutrition store garbage, and that isn't afraid to show their face, dig in, and train with you, and so on.
One other comment about Sagi: Sig surrounds himself with experts. His entourage includes the very best of whatever discpline...law,...IT....health...dentist. Sig knows how to make a plan for success, execute it, and come out on top. That's the kind of trainer you should find.
