Treadmills are the most popular piece of exercise equipment, cornering 33 percent of the exercise equipment market. Remember, however, that no single piece of equipment can do everything. Your best bet would be to choose equipment that works the whole body, rather than something that works only one part of the body. Next, look around your home to see how much space you have. This will have a major impact on the size and type of machine you buy.
Some exercise equipment is collapsible or can be rolled out of the way, which is very convenient.
If you have a spare room, den or basement that can become your in-home fitness center, that's even better. Make it a point to comparison shop. Read consumer or fitness magazines to find how they rate different types and makes of equipment. Your results with the same equipment may be very different from those of the people in the ads. Also, be wary of claims that promise amazing results in a short amount of time.
