Precor EFX 5.21 is a 162 pound machine and has the capacity to accommodate up to 300 lbs. The ramp is made of welded steel and covered with a coating of black powder to make it strong and highly durable. It comes in the dimension of 76” X 29” X 62”. Dimension of the foot pedals is- 7” (width) X 15” (length). The trainer has the Warm Brown along with Warm White accents and black CrossRamp.


Assembling this trainer requires two people. The manual is quite self explanatory so I didn’t have to face many difficulties to assemble it. However, you need to make sure that you have all the tools available to complete the whole process. One of the biggest downsides with this machine is that it doesn’t have any transport wheels. So you need to assemble the system exactly where you are planning to keep it because it is not very easy to move the machine from one place to another.

Crosstrainer Technology

The EFX 5.21 Elliptical Fitness Crosstrainer ensures smooth, low-impact, natural workouts which has helped me to achieve maximum result within a reasonable period of time. The fixed handlebars designed for lower-body-focused training is a perfect feature for lower body exercises. This trainer matches the natural motion for running and walking. The smooth experience ensured by the crosstrainer technology makes workout easier than ever. Precor EFX Ellipticals are reputed for ensuring lower Rate of Perceived Exertion (RPE). Means, you will be able to train for longer hours and more frequently to get better result within a short period of time. However, they don’t have any program for the upper body workouts. To me, this is what prevents it from being a “complete” trainer. Cross ramps can be adjusted manually within the range of 15-25 degree.

Heart Rate Monitor

Telemetry and Smartrate technology is installed in the system which allows me to monitor my heart rate on the display. The handheld heart rate monitoring sensors are installed in the fixed handlebars to give you accurate reading. You can also use the chest strap transmitter but it has to be purchased separately as the transmitter doesn’t come with the package.

No cooling fan

There is no cooling fan installed. This is something I dislike about this machine. I think the cooling fan would make it even more user friendly and would allow the user to continue working out for much longer as it would help to keep the body temperature at an expectable level.


Precor EFX 5.21 has a 4” X 3” single color LCD display. To be honest, it is just a normal display system that shows different information about your physical condition while training. The information that you will be able to see on the display includes: Calories, Heart rate, Distance, Program profile, SmartRate®, Resistance level, Strides per minute and duration.




This trainer has 8 workout programs installed in the system. I think in comparison with many other machines, the number is a bit low. But it does have all the basic essential ones that I found to be quite useful. The programs include Heart Rate, Cross Trainer, Hill Climb, Fat Burner, Interval, Gluteal, Weight Loss and Manual. The trainer also includes 16 electro-magnetic resistance levels ensure variations in your workout process.


The deal includes Lifetime warranty on the welds and frame, 5-year warranty for the machine parts (both mechanical and electrical parts), 5-year warranty for the wear items and labor warranty of one year.

Precor EFX 5.21 is an expensive elliptical but it does include some excellent workout features that is designed to give the ultimate result. It is highly durable and very easy to operate. So you can continue using this trainer for a long time without facing any problems.
