The Precor 5.33 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 5.33 is Precor's top end elliptical. It has the moving arms and awesome program features but it does not come with the adjustable incline ramp like the Precor 5.17, 5.21 and 5.23 ellipticals have. If you have to have the best and you love the moving arms, this choice is easy.
