Precor EFX 5.25

Reviewers say that the Precor EFX 5.25 elliptical trainer is an excellent, near-club-quality elliptical trainer that can hold up to regular use, even by the most serious exercisers. This machine is solid and durable, and users say it feels stable while exercising. Reviewers praise the automated incline, which helps target different muscle groups. The adjustable stride length, between 18.5 and 20 inches, accommodates users of varying heights. Other popular features include 16 resistance levels and eight workout programs. The Precor EFX 5.25 supports wireless heart-rate monitoring, but it doesn't come with a chest strap, an accessory that is often included with ellipticals that cost less.

Reviewers are impressed with the warranty, which includes lifetime coverage for the frame and one year for labor. However, Precor has shortened the parts coverage for the EFX 5.25. Those models sold after Dec. 1, 2010, have a five-year parts warranty, while machines sold prior to that date came with 10 years of parts coverage. Assembly is relatively straightforward, but the Precor EFX 5.25 is bulky and heavy, and it takes some time to put together. If you don't need a club-quality elliptical trainer, reviewers recommend the Sole E35 (*Est. $1,170) .
