Here are the main factors that runners should consider when shopping for a treadmill:

  • Stability. Choose a durable model that won’t move, sway, or create excess noise. This is especially important if you plan on running at high speeds.
  • Motor capacity. Look for a treadmill with a quality motor that offers at least 3.0 continuous horsepower (CHP). This is essential for training at fast speeds and high inclines. Note that if you weigh more than 200 pounds (91 kg), you’ll want a motor with at least 3.5 CHP.
  • Belt. Consider the length of the belt, especially if you’re tall or have a long stride. Also, keep in mind that thicker belts prevent wear and tear and won’t have to be replaced as often.
  • Incline options. Many treadmills offer incline options for adding variety and intensity to your workouts. Some models even offer automatic incline adjustments during live classes.
  • Extra features. Treadmills vary greatly in the special features they offer. For example, while some provide access to live and on-demand workout classes, others come with programmed workouts and device trays.
  • Space. Consider how much room you have available. If space is limited, opt for a smaller treadmill or choose a foldable option.
  • Budget. As treadmills can range from a few hundred dollars to several thousand, it’s important to decide how much you’re willing to spend.

Once you’ve narrowed down your search, consider trying the treadmills at a store or gym. However, if it isn’t possible to test them out in person, reading customer reviews online can be an effective alternative.

Whether you’re dealing with bad weather conditions or don’t feel safe running outside, treadmills make it easy to take your cardio workout indoors.

Before purchasing a treadmill, consider factors like price, motor capacity, training options, and available features.

By using this list as a guide, we’re confident that you’ll find the right treadmill for your running needs.
