Pass by Fort Lauderdale Beach on a Saturday morning and you can't help but notice personal trainer Bob Weinstein, a.k.a. "The Health Colonel," in full camouflage regalia and combat boots exercising with his "troops." On the home page of Weinstein's website, www.nomorecrybabies.com, there's a link that says, "Here's why Bob trains on Fort Lauderdale beach." Click it and it leads to a picture of the sun rising over the horizon -- no words required. But we can scribble a whole list of reasons why this long stretch of sand, with its wide brick path, should keep you motivated. First of all, there's free parking at the corner of A1A and Sunrise Boulevard. From there, you can choose to run north and watch the surfers, run south to Las Olas Boulevard (1.5 miles), or run west and tack on a couple of loops in shady Birch State Park. For a challenge, go barefoot on the beach sand. Along the way, shoppers at BeachPlace, drinkers at the landmark Elbo Room bar, and even the colonel himself will be cheering you on -- and checking out your hot legs.
