Seven-time Tour de France winner Lance Armstrong may have set aside his spandex-clad cycling career, but the record-holding athlete remains as active as ever. We couldn't resist touching base with him - between his running marathons and opening multiple 24 Hour Fitness clubs - to see how he likes "retirement" and to snag several frequent-flier-friendly biking and workout tips. - Scott Steinberg

Do you have any fitness tips for all the road warriors out there? Yes. Do yourself a favor and get into a steady routine, even if that means taking the odd day off. Not everyone has to be in the gym every day. Just get on a steady program. Cycling isn't the only thing you should do to stay fit, either, and it certainly isn't the only thing I do to work out, myself. Try activities like swimming, running, and kayaking, which burn calories quickly and help build cardio ability over time. And if you ever feel like slacking, just check the scale, which is the one thing we pretty much all have in our bathrooms. It never lies.

What are things people should watch out for when in the gym? I can't say it enough: Concentrate on your form and technique when you're exercising. It's crucial. You don't have to work with a trainer to maximize workouts, but if you don't have proper form, if it's incorrect, you won't just wind up not getting an optimal workout; you may be courting potential injury, which is even worse. So if you have questions, don't hesitate to ask them. It may seem embarrassing at first, but it's better than the alternative.
