No doubt about it -- exercise helps circulation and can give you a healthy glow. But for your skin's sake, you ought to walk for exercise and not run.

When you pound the pavement, the force of your body jostling can cause collagen to break down, which can lead to sagging skin, says dermatologist Dennis Gross of NYC. Hey, running is not so great for your knees either. I guess walking is the way to go -- although I don't plan to abandon the run just yet. How about you?

Just wanted to wish all of my fellow Americans a very happy Fourth of July, and to remind everyone why we celebrate. Of course politics can be rough, and the economy sometimes varies, but those things pale in comparison to all that this country has to offer. As I was explaining to my three and five year old children this week, we celebrate our freedom this Friday. As Americans we are able to choose our jobs, choose our religion, choose our spouse, choose our homes, and have as many or as little children as we'd like to have.

Nothing is perfect of course, but America is perfect for me. I rarely walk by a man or woman in uniform without thanking them for their service, nor an elderly man proudly wearing his baseball cap describing which branch of the military he served. I value the local and state law enforcement officers for placing their lives on the line each day to protect ours. I'm even grateful for the sometimes messy brood of politicians we elect to run this beautiful country of ours.

Lastly, I'm grateful for the nation of Americans. Thank goodness the majority of us are really good hardworking people. The good certainly outweigh the bad. I thank you for voting, working, educating your children, volunteering, helping strangers, and just making this country what it is today. I love it here. I'm proud to be here, and I'm grateful to those who laid their lives on the line to provide my family and I the simple yet irreplaceable luxury of freedom.

Not only are Victoria's Secret FitFlops not likely to pump up your fitness level, they're actually prone to throwing you off your stride, causing pain in your lower legs and feet. This, according to a study released last week and presented at the annual meeting of the American College of Sports Medicine in Indianapolis, comes after experts observed 39 college-age men and women walking on a special platform wearing flip-flops and then walking across the same platform wearing athletic shoes. The platform measured stride length and vertical force.

The bottom line: Flip-flops, unlike sneakers, cause shorter strides and require heels to hit the ground with less vertical force. This altered gait explains some lower leg and foot problems in people who often sport flip-flops, like college students.

If you're worried about pain in your own legs or feet, take this common-sense advice: Limit the use of flip-flops. Replace them every three to four months too, just like you'd do with athletic shoes. And perhaps rethink your trip to Victoria's Secret for those Fit, and albeit very cute, Flops.

Q. Brrrr Fitz! I live in the waaaaaay cold and am already starting to feel the flab. It's too cold outside to go for runs like I normally do. I can't afford the gym and don't want to look like the snowman on my lawn. What do you suggest? Rick

A. Eeeek Rick! I can't imagine. Literally. I can't imagine, because I've lived in Florida all of my life. It's about 80 degrees outside right now. I have been in the cold and snow though, Norway seems to have a lot, and I do have some recommendations. First, there are a ton of things you can do at home. Sometimes it is just too hot to train outside where I am, so I end up in the same situation you're in now (but opposite).

A treadmill would suit your running needs, but if that investment is too much...here are some ideas. Move the furniture and--jump rope, run in place, do jumping jacks, jump on a mini-trampoline, hit a heavy-bag, dance, do step aerobics, squat jumps, video training, gliding disks, free weights, pull-ups, push-ups, squats, or crunches.
