  • Perfect for joggers

    I jog practically everyday and this treadmill has been a workhorse. It is really sturdy. Because of that you will need 2 people to lift it out of the box/assemble.

  • It's a Beast!

    I just got this end of July and a few things of note:

    1) EXCELLENT Customer Service from Xterra!
    2) EXCELLENT communication from shipping company to me! The guy who delivered was super nice and a great guy.
    3) It's a BIG treadmill. We live in an apartment, and it's basically another piece of furniture. However, it's worth it!
    4) GREAT VALUE! For the price, you can't beat the quality. I'm very pleased!
