We all want to be stronger, faster, fitter. Look no further than the $22 billion fitness industry, with its fad workouts, would-be gurus and gimmicky products, for proof. But, as any scrawny, pimply, hormone-wild teen can tell you, it ain’t easy.
It takes hard work and dedication to improve athletic performance (and to look good in a tailored shirt), sure, but it also takes specialized knowledge that few possess. Long, slow distance alone won’t earn you that sub-three-hour marathon, and marathon bouts of machine-based circuit training won’t make you massive. That’s where personal coaches come into play, if you can afford them.
And if you can’t, well, there are these books. Chock-full of training plans, practical tips, hard-won advice and timeless wisdom, each offers invaluable information for taking your fitness — and thus your sport, whether it’s running, golf or CrossFit — to the next level. Some have stood the test of time (our oldest selection is 22 years old — almost ancient in the world of sports physiology) and others outline the latest research-based innovations. But all of them will improve your athletic performance from the comfort of your favorite reading chair.
