There are several factors to consider when shopping for a treadmill:

  • Training needs. To help narrow down your search, it’s important to consider how you plan on using your treadmill. Do you need high speeds for interval training? Or is an under-desk treadmill for walking a better fit? Also consider the available incline levels and preset workout programs.
  • Desired features. One of the main differences among treadmill brands and models is the available features. For example, while some offer Bluetooth speakers and touch screens, others include LCD screens and heart rate monitors.
  • Size. Especially if you have limited space, you’ll want to pay close attention to the dimensions of each machine. Many treadmills also have folding mechanisms, allowing for easy storage.
  • Running deck size. While a 48-in. (122-cm) running deck will work for most runners, if you’re taller than 6 feet (183 cm) or have a long stride, you’ll want a deck that’s at least 54 in. (137 cm) long.
  • Budget. In addition to the price of the machine, make sure to factor in costs such as shipping, installation, and fitness app subscriptions.
  • Customer reviews. For valuable insights into the quality and durability of a machine, be sure to read several customer reviews before making your final decision.

Treadmills offer an effective way to stay fit in the comfort of home.

Plus, with so many types available, there’s sure to be a product that fits your fitness and budget needs.

Just make sure to consider factors like price, portability, training options, and available features before you buy.
