While visiting Tucson's Canyon Ranch health and wellness resort, I spent a few hours with a fitness instructor who evaluated my body composition, flexibility, muscle strength, and cardiovascular performance. After offering me a grade in each of these areas -- my muscle strength was average, for example; my cardiovascular performance very good -- he gave me all sorts of tips and techniques for reaching a high level of fitness. He armed me with a variety of options, and I now have a solid collection of exercises in my bag of tricks. One thing I don't have in my bag, however, is a need for a lot of fancy equipment or gear.

This fitness instructor told me he once knew a college football player who had the most gorgeous body he'd ever seen. He'd picked up not one weight in his pursuit of such beauty. He merely used his own body.

We are everything we need to get fit. Our bodies are tools. We can use them to do push-ups, sit-ups, pull-ups, dips, squats, lunges, wall sits, planks. We can walk, run, sprint, jump, balance, and more. We need nothing more than our own body weight, really, to achieve greatness. So before you go out and spend a fortune on weights and bands and balls and other contraptions, try using what you've got -- yourself.

Thanks Canyon Ranch for the inspiring fitness wisdom.
