Searching for a treadmill years ago was easier - there were only a few models to choose from. These days equipment selection has greatly expanded and grown in sophistication. The price tag is still high on the best models, often running at least $1000 and sometimes much more.

Advantages: Let's look at the advantages of using a treadmill. If walking or jogging is part of your physical fitness program, the treadmill affords several significant advantages. No more jogging in bad weather. No running outdoors at night or tripping over potholes or uneven surfaces. Another plus: if a dog is chasing you, it must be your own.

With a treadmill, you will not be wasting time traveling to and from a fitness club. Also, a treadmill cushions the shock to your knees and feet, minimizing injury. Then there is the option to multitask. Reading or viewing Television while you exercise can be an option. No wonder Treadmills remain the most preferred home fitness machines; they supply over 50% of the market.

Five keys to finding the best one for you:

1. Overall size of the unit must fit in the space you have. Folding units are generally shorter and can be folded to store. The downside for taller people is the shorter deck may be uncomfortable with a longer stride.

2. Construction: Look for solid construction which tends to provide the user with an increased sense of stability during use.

3. Features: Look for easy to read displays and simple control. Many treadmills come with heart-rate monitors and programming selections to match your fitness level. Typical handy features include drink holders and book holders. A few actually include a TV!

4. Price and warranty: Besides the base price, is shipping included? Can you pay out over time with deferred interest? Does the warranty cover parts and labor?

5. Customer reviews: Take a look online to see what other customers think. Be sure to check multiple reviews to get different perspectives.

Note of caution: be certain to maintain a safe workout space for you and your family members. Small children particularly are susceptible to injury from treadmill belts and moving parts. Keep them safely away from the equipment during use.
