This is a good place to start, especially if you're new to the Web or new to exercise (or both) and you have time to browse. Your host Charles Rotblut, a certified personal trainer, organizes links into categories such as Aerobics, Golf, Nutrition, Running, Weight Lifting, and many, many others. He also indicates whether the sites are commercial or non-commercial.

Fitness is not just for twenty-somethings. Several years ago Gypsy, who has 15 children and 26 grandchildren, found herself unable to keep up with the youngsters. That began her interest in exercise, and today she teaches aerobics, boxes, and lifts weights, among many other activities.

She also maintains an informative and friendly site for exercisers -- and non-exercisers -- of all ages. Her sense of humor infuses every page, and you will find a lot of good advice for life in general, not just fitness.

Her essays cover specific topics such as body control ("Just When I Think I Know Where It's At, Some Body Moves It") and sports ("To Me, Boxing Is Like Ballet, Except There's No Music, No Choreography, and the Dancers Hit Each Other"). The Muscle of the Month section contains step-by-step instructions, complete with photographs, for several strength-training exercises that target specific muscle groups.

This holistic e-zine covers a range of topics from relationships to nutrition. Its fitness section (called, not surprisingly, Fitness Matters) introduces you to T'ai Chi and Yoga, with advice on how to find a T'ai Chi teacher and an animated demonstration of the Pushing Hands technique.

"Running on Full" targets pregnant women with articles such as "Running and Breastfeading" and "Pregnancy and Healthy Eating."

Discussion groups and bulletin boards invite your participation. In "Ask the Fitness Trainer," you can e-mail your questions for a free answer, or sign up for a customized fitness and nutrition program; prices for this service range from $9.95 to $69.00. This is an attractive information center and well worth a bookmark.

The focus here is on getting active, whatever that means to you.
