Steelflex XT 5600
Reviewed by TreadmillReviews.com
The Steelflex XT 5600 has a few upgrades from the 4600, but not nearly enough. The only things that have been added to this model is a 12% incline, a tread belt length of 20″ x 54″, and the weight capacity 330 lbs. The actual number of programs in the console have been reduced from the 4600 model. There are 18 programs that are displayed on the 3 window LED screen. It doesn’t seem to be getting better with the features or specs in these higher model numbers. You can find much better deals out there from bigger brands like NordicTrack, ProForm, or Smooth.
