Werner Günthör is one of my favorite examples of nature vs. nurture. His muscle fiber profile didn’t exactly scream “world-class explosive athlete.” Yet he became a three-time world champion and one of the greatest shot putters ever. His fast-twitch fibers became large enough to completely change the functional makeup of his muscle. And when the training stopped, much of that adaptation went with it. Genetics matter. But they don’t tell the whole story. Your starting point isn’t necessarily your finishing point. #strengthandconditioning #power #powertraining #jumptraining
