The Precor EFX 5.21 Elliptical Fitness Crosstrainer is a compact fitness machine designed for low-impact cardio and toning within a small workout area. What it lacks in bulk, the EFX 5.21 more than makes up for in features. The unit offers eight pre-programmed workouts, including warm-ups and cool-downs, as well as 16 levels of adjustable resistance. Unlike many ellipticals, this model's handlebars are fixed, focusing the workout on the lower body.

Precor is well-known for its quality elliptical trainers. Since 1980, the company has been manufacturing fitness equipment with comfort and safety in mind. The EFX 5.21 is no exception. The adjustable CrossRamp functionality offers tri-position selection to target various muscle groups while the fixed handlebars offer multiple position options to ensure good posture. And with the smooth, natural stride and fitness metrics monitoring--including heart rate, distance, resistance, calorie burn, time, and strides per minute--the EFX 5.21 offers a continually-challenging, comfortable workout that will have you coming back for more.
