As recent studies have shown, people are getting busier and busier each day. Other studies have shown that more and more people realize the benefits that exercising can have on their health. Not being able to go to a gym, because that would be a schedule modifier, people turn to home fitness machines(such as treadmills) to solve their problem.
Today this is a pretty general issue, so the demand for such equipment has increased exponentially - and amongst these, treadmills enjoy a lot of popularity. Even the experts consider that a treadmill is an excellent purchase for such a purpose, since it satisfies the need for exercising, it's never going to be old-fashioned or lose popularity. When you make a treadmill purchase decision, it should be an informed one - it's not that difficult, but generally you should know what you expect from such a machine and adapt the preferred features to your needs.
It's important to try it out prior to making the purchase - see how you feel it, how much it fits "you". If you aren't able to do that(like when making a purchase through the Internet), just read out some reviews and see what others are saying about it. Here are a few important things that should count in your purchase decision:
* stability is important, as much as the running belt is important (at least 18-20" wide and 48" long) * the running surface should be a low impact one, since it protects your joints, knees or back from potential damage by a special technology * reachable emergency shut-off, side rails and safety bars, these are also essential options * another important sign of quality is the warranty(and don't forget maintainance and service) * continuous rated motor - 2.5 to 3.0 hp * the reachable speed is also an important factor, since it should meet your goals (from 0.1 to 8 mph should be enough - this includes both walking and running)
Above all those important specifications, there are a few more that would sure make your life a lot easier: a fold-up design would make the storage much easier for you; I'm sure that a heart rate monitor would be of much help; and a computer console that would include a number of workout routines would be very important also.
As a conclusion, when making a treadmill purchase, you should consider all the mentioned aspects and any other one that you can think of to optimize your workout; only you know what's best for you and what's closer to your needs.
