An essential part of a healthy life plan includes an exercise routine which will not only work around your schedule, but something you can do year round and anywhere you want to be.

Running or walking is one of the best forms of exercise compared to other exercises such as Pilates, or weightlifting because of the natural way your body moves. You can also perform this exercise anywhere you are and need very little equipment. As a result, you will be more likely to continue running/walking throughout your life. If you are serious about taking advantage of this natural form of exercise, you will need to prepare yourself for unexpected events such as rain, snow or pesky neighbors. The safest and most convenient way to run or walk is by using a treadmill.

If you are considering buying a treadmill, there are a few things you should familiarize yourself with before actually going out (or online) and purchasing one:

1. Price: When it comes to treadmills, the more you pay the better machine you will get. This is because you are paying for added accessories and more stability. Compare it to buying a car. The basic model will do the job. You might become bored with the lack of extras, but if you are on a budget, this will do fine for you. Remember, you can always upgrade. Then there comes the mid-range model. More accessories are added, which can make the ride smoother and a bit more lively, and the price is still pretty sensible. If you are really in the mood to splurge, the high quality treadmills will shock you with more bells and whistles than you could ever dream of. Some people, however, may become overwhelmed by all the present courses, heart monitors, incline levels, cup holders, book holders, and digital programming offered by top-of-the-line treadmills. Browse around online to see which add-ons you will enjoy and which you can live without, this will narrow down your choices and keep you from getting too carried away by the latest and greatest.

2. Stability: Make sure you wear your workout clothes when shopping for treadmills, you will want to "test drive" certain models to see if they are stable enough for your running/walking form. You will want to be cautious of machines that shake or rattle when you are going full speed. A good stable ride will make a world of difference in your safety and will also cut down on the noise level. Also take into consideration the motor volume, if you plan to read, watch the television or listen to music, a noisy motor will quickly become a big distraction.

3. Size: In the store and especially online, size can be deceiving. Make sure to measure the room which will be housing this machine and allow for plenty of "walk-around" space. When you are buying, check the dimensions. Size is not always an indicator of quality.

Treadmills might seem a bit pricy, but they will pay for themselves over time with convenience and indoor safety. Plus, your exercise routine can be more consistent with a treadmill. Look online for bargains. You might be surprised by the prices and options available. With a little research, you will surely be able to find the perfect treadmill for you and your budget.
