What to consider before investing in a treadmill?

Before investing in a treadmill, there are a few crucial points to not only note but consider.

Size 

If you're someone living in a large apartment or home, size might not be one of the most important factors on your list; now, in the case, you're in a cramped apartment? You're dialing-on how big or small your potential machine is. 

Incline range 

Another deciding factor might be the incline range and how high the machine does (or does not) go. Most of the machines on this list feature an incline range of 0% to 15%; however, the NordicTrack X9i Incline Trainer goes up to 40% making it the best treadmill for hill runs.

Pre-set programs 

Another deal-breaker? What pre-set programs does your potential machine offer? See, pre-set programs are crucial for those struggling with motivation or lacking guidance, but those machines come at a cost. 

Top speed 

Always consider the top speed of a treadmill before purchasing. This will depend on your fitness level and whether you are using the machine to walk, run, jog or sprint.
