Sick of all those lists telling you how to get fitter, faster, leaner, healthier in ten easy steps? Forget ten. Try five.

1. Change it up every 5

Other research shows that you can burn upwards of 20 percent more calories if you start at a brisk pace, then finish a bit easier. So hit the treadmill with extra vigor up front, and ease up as you go.

3. Find 5 new routes

Does the idea of running or cycling around the same park at the same time of day -- again -- bore you? Mix it up and choose a new route. Denver has more than 200 public parks, 100 miles of running trails and over 850 miles of paved, off-road bike trails. Chances are there's one -- or five -- that you haven't used just a few minutes away. If you're not familiar with the terrain, walk it first. Running may burn more calories, but a
