The EFX 5.31 is the opening of the high end Precor elliptical lineup and one of the best values that Precor makes. It is also our Best Buy award winner for 2014.
The EFX 5.31 is really the elliptical you should buy if you want a Precor elliptical and a great value. Many people will bypass this model because it doesn't have articulating arms, but the fact of the matter is that total body ellipticals don't give you as good an workout as lower body only. At least that's what the research tells me.
