The Steelflex XT 4600 is practically identical to the 3600 model. The only real difference is in the number of programs in the 4600. The XT 4600 has 21 workout programs that cover manual, fat burn, interval, running, and cardio. The motor power is still 2.4 chp and the tread belt is still 19.5″ x 54″. The incline can go up to 10%, the max speed is 10 mph, and the weight capacity is 300 lbs. These specs are not up to par with what you can find in a similarly priced NordicTrack, ProForm, or Smooth model. The warranty is not all that great either. It covers frame for life, motor for only 3 years, and parts for 1 year. A great alternative with awesome features as well as better specs would be the NordicTrack Commercial 1750. It’s one of the top treadmills selling on the market today and has a cheap price tag for all that it gives you.
