Do I need high-tech gear like a pedometer?
"Gadgets are great if they're easy to use and enhance your training," says Rocker. The trick is to choose the right tool for your needs. A heart-rate monitor lets you track whether you're in your optimal training zone so you can adjust your intensity. Pedometers are amazingly simple, functional, and inexpensive. "The benefit of pedometers is self-motivation; they give you an easy measuring system," says Joy Prouty, a Reebok master trainer and ACSM-certified health fitness director. One caveat: If gear is too complicated or detracts from walking pleasure, leave it at home.
