Although price is an important factor, your health is most important factor. And a treadmill is an investment in your health.

Do you want to wreck your joints or give yourself permanent back problems just to save a couple hundred bucks?

Unfortunately, this happens all too often. I know of one woman who did permanent damage to her hips because she bought a cheap treadmill with cheap cushioning and then ran on it. Within 4 months, she was in so much pain, she couldn't even walk on her treadmill.

But it doesn't have to be this way. You CAN find a high quality treadmill for a reasonably low price - if you know where to look.

While it's true that not all of us can afford a $4000 commercial treadmill, there are higher quality treadmills out there for under $1500 and even some under $1000. Don't sacrifice your health just to save a buck.

Bonus Mistake #4): Not Considering Your OWN Personal Workout Needs Before Buying

That’s great that you found a quality treadmill for $999. But have you considered fact that you are 6 feet tall and that treadbelt is only 52” long?

When shopping for a treadmill, many people fall into trap of ONLY looking at treadmills and never looking at themselves.

For example, are you tall or are you planning to run a lot? Then you need to make sure treadbelt is at least 55".

Are you, or is someone in your household a little on sturdy side? Then it’s probably best to get a treadmill especially built to take heavier weights.

Do you have back problems or a weak back? Then if you want a folding treadmill, it might be better to purchase one with a power folding option so that you can reduce strain of heavy lifting.

Remember to consider your own needs when looking at treadmills

Regardless of which treadmill you choose - try to steer clear of these common mistakes and you'll save yourself a load of grief (and a ton of money!) Good luck and have fun!
