1 START SMALL

If an hour of physical activity is too much, start with 30 minutes, or even 15 minutes. Walk, skip, swim, run, bike or jump-rope your way gradually to fitness. Increase your time and speed when you're ready.

2 SEEK VARIETY

Ideally, you want to create a well-rounded fitness routine that includes cardiovascular work, strength training, flexibility and balance.

3 FUEL UP PROPERLY

Nutrition, hydration and smart meal timing are a must. Don't skip meals, especially breakfast.

4 DON'T SWEAT THE SMALL STUFF

So what if you can't do five miles a day, or curl the 25-pound dumbbell? Half of that is fine. Just start and never stop. You'll be surprised how quickly you progress.

5 NEVER GIVE UP!

At some point, you are going to reach a plateau or suffer some setback. That's just life, and you have to hang in there! Focus on the journey, not the destination.
