Our Rating

Rating: 85/100. The high quality EFX 423 is the entry level model in Precor’s Precision Series, the brand’s top line of luxury elliptical trainers for home gyms. Precision Series ellipticals have earned their high price tags; they offer club-quality workouts, feature Precor’s patented smooth motion, and carry 10-year parts warranties. The EFX 423 is most different from the others (the 425 and 447) because its arm bars are stationary; it’s built exclusively for training the legs and glutes. Excellent lower body training gets accomplished with help from this machine’s most dramatic feature, a motorized incline with maximum 40 degree tilt.

The data fields shown during training are Time Elapsed, Time Remaining, Calories, Calories/Min, Distance, Strides/Min, Average Strides/Min, Resistance, Percent Complete Heart Rate, Target Heart Rate and SmartRate® Zone.
