Dr. Jordan Metzl Metzl shares his fitness expertise in a new book.

Say it isn’t so? One of the most fit, most athletic, and perhaps most emphatic sports medicine physicians let it fly that he is human.

“I have some knee arthritis,” says Jordan Metzl. “Instead of easing off (exercise), I have built up strength around the joint. That has really helped.”

Make that helped immensely. Consider this: The elite athlete plans to compete this year in marathon No. 30 and Ironman triathlon No. 10.

Metzl, 45, shares his fitness expertise in a new book, The Athlete’s Book of Home Remedies, 1,001 Doctor-Approved Health Fixes and Injury-Prevention Secrets for a Leaner, Fitter, More Athletic Body! (Rodale). Several former presidents of the American College of Sports Medicine and professional and Olympic team physicians have praised the book for its accuracy and methods to prevent injury.

He knows athletes of all ages get hurt. His patients, from professional athletes to young and older weekend warriors, tell him the Internet is where they turn to self-diagnose.

His advice? Don’t.

“I wanted people to have good, accurate information and to know when to seek help. There’s too much bad information on the Internet.”

So for all the do-it-yourselfers, the first part of his book will be one of the most popular. Nine chapters are devoted to what can go wrong, from head (concussions, broken noses) to foot (stress fractures, neuromas). The book features dynamic anatomical illustrations, descriptions of the pain and other symptoms, treatments, when to call the doctor and how to prevent the injury from recurring.
