The more you honor your integrity, the more dignity you have. Your promises to yourself must be so important and easily kept that you'll reach out and grab them every single day -- because you want what you've promised yourself!

What this study seems to say is that if your exercise of choice is walking, it has to be more than a stroll around the block if substantial health benefits are to be achieved.

Take a second to think about your gym routine. Got it? Now, I bet you feel pretty good about the fitness moves that you've incorporated -- you're hitting the big muscle groups, and plus, these moves are so popular that they have to be effective. Right? Wrong.

Make the most of your time. A quality, intense workout always exceeds a long, mediocre workout. On the flip side, remember that too much of a good thing is still too much.

Whether you hit the gym first thing in the morning -- or, like me, end your day with a long-distance run -- it is all too easy for us to counteract our workouts by our actions throughout the day.

Let's exercise and do it well! That is a major ingredient in maintaining a healthy body and a healthy soul.

Cellulite, like male-pattern baldness (trust me) is genetics' way of reminding us that life isn't fair. Those of us who are "put out" -- but unwilling to resort to the knife -- still have some options. At least you women do. Me, I'm going to have to hope year-round hats stay in style.

March Madness is in full swing! If your favorite team is still in the lead, you may feel like you can't miss a second of the game. Rather than sacrifice your workouts all weekend because you have to keep your eye on the TV, why not work out with your friends as you watch all the fun?

Getting to your goal is going toward where you want to be, and making a comeback is going back to where you were before. Getting to a goal is a challenge that takes discipline, willpower and dedication. But making a comeback is even harder.

There is no question that in order to become skillful at any sport or fitness activity, you need to participate in and practice the activity. But if that is all that is required -- practice, practice, practice -- how come not everyone that practices a lot excels at what they do?

Maybe it's because running is so quantifiable, but most runners I know love "magic bullets." We want to improve -- it's why we run in the first place -- and we'll typically try anything (within reason) that might help us run more miles or faster times.

The patterns that you repeat on a daily basis will eventually form the identity that you believe in and the actions that you take. You can transform your identity and become the type of person who doesn't need motivation to perform well.

Study after study tells us that exercise is one of the most important behaviors for maintaining overall health and preventing disease. But even though...

High-intensity intervals can be classified as brief exertions of maximum output, usually in the range of 20-40 seconds of intense activity, followed by a designated resting or recovery period. You could complete an entire high-intensity workout with minimal equipment in 20 minutes or less.

As you can see, a workout to improve sports performance is a bit more complex than a weight-loss workout. But when implemented properly, it can not only help you run faster, jump higher, and push harder, but also keep you from getting injured.

Weight-loss workouts seem to be a dime a dozen, and easily found on fitness websites or in magazines. But what if your goals are more sport-specific and less focused on aesthetics?

I am a big believer in the power of group fitness. Whether it's the energy of hundreds of yogis sweating together at an outdoor festival or a group of 40 spinners rocking out to Kanye remixes, group fitness inspires healthy camaraderie and shines a bright light on the world of wellness.

Fortunately, the actors I have worked with are all aware that practicing unhealthy dieting is not a viable choice when it comes to everyday living. It is not sustainable and does not make weight loss permanent. Many are fantastic cooks who love to prepare foods for themselves and their families.
