In order to find the right treadmill, it's important to know how it will be used and who will use it. Make a list of everyone in your household who will work out on the treadmill and consider what their fitness goals are. The more use that your treadmill will get and the more intensive the workouts will be on it, the more important it is that you buy a high quality model. For example, if you plan to use the treadmill primarily for running, you'll need a strong motor. If you will mainly use it for walking, you can go for a model with a lesser motor. It also matters how many people in the house will use the treadmill. If there are multiple runners who'll workout on the treadmill, you should purchase a high quality model. Consider the weights of the treadmill users as well. If both a 200 lb and 160 lb person are going to use it, you don't want to purchase an underpowered model. You should also think about what your household's fitness goals are. Some models may be better suited for individuals who are trying to lose weight, while others are better for people who are trying to enhance their athletic performance. Another important decision to make before you shop for a treadmill is where you intend to keep it. If you have a room that's already set up as a home gym, you may have enough space to leave the treadmill out permanently. However, if you're short on space, you may wind up putting it in your bedroom, family room, or another space, and you won't necessarily want to leave it out all the time. In those cases, a folding model that you can easily tuck away in a closet or corner is your best option. On average, most treadmills are approximately 77 inches long by 35 inches wide. Non-folding treadmills tend to offer a sturdier deck and frame, so they're usually a good option for avid runners. Folding models come in a variety of price points. The budget folding treadmills are typically best suited for walking, while the higher cost folding models are good for a mix of walking and running. Keep in mind that your treadmill will need to be near a power outlet. When you're looking for a space in your home for your treadmill, make sure there's a power outlet nearby. Before you start looking at treadmills online or in stores, it's important to decide how much you're willing to pay. Treadmills can cost anywhere between $200 and $4000. On average, though, you can expect to pay about $1000 for a quality treadmill. Cheaper treadmills are better suited for walkers, while runners typically prefer mid-range to high priced models. Choose a budget for your treadmill, and look for the best model that you can afford. If you have your heart set on a high end treadmill that doesn't fit your budget, you may want to consider purchasing a pre-owned model. You can often find sales on treadmills and other fitness equipment at the end of the year or beginning of a new year when many people are making fitness-related resolutions.
