The Precor 5.23 is a very heavy duty and program packed elliptical trainer. This elliptical has the same motion and feel as the Precor ellipticals found in the gym. If you want to rent an elliptical that will match your gym experience, this is it! The 5.23 was Precor’s elite home model until 2008 when they gave their ellipticals a cosmetic overhaul. In many respects this is the best home elliptical they have ever made.
