This handsome machine is a smaller version of the ellipticals that ProForm is known to bring into the market. Called the ProForm XP 420 Razor Elliptical, it has a mechanism known as "Perfect Motion Technology" that measures a mere 3.75 inches - only half as wide as other elliptical mechanisms.

This technology makes for more compact glides and strides for a more enhanced workout. Quality is not sacrificed as it also has an adjustable stride feature, making it possible for you to alter the length of your stride and work various muscle groups for optimal results.

You'll definitely get a thorough exercise from the ProForm XP 420 Razor Elliptical's 6 different workout programs, target pacer, and digital resistance. The latter lets you adjust the resistance for better calorie-burning capacities and greater workout intensity.

This unit can easily be shared with other members in the household as it features 4 different personal training programs where you can concentrate on a certain fitness objective - aerobics, weight loss, or your own personal fitness goal.

One of its more unique features is the Target Pacer. To get the most out of every training session, the ProForm XP 420 Razor Elliptical's Target Pacer makes use of an indicator light so you can tone down your activity or rev it up a bit.

When combined with its EKG Heart Monitor which works via sensors on the elliptical's ergonomic handlebars, you'll ensure optimal results for your regular workouts.

The Target Toning Trainer Workout feature focuses on specific body areas and lets you tone certain groups of muscles. The CoolAire Workout Fan helps you feel more comfortable during your training sessions as it's built into the console itself.

There are varying reactions as to whether the ProForm XP 420 Razor Elliptical is easy to assemble or not. Some can put it together in 2 hours or less, while others have even had experiences when there were missing parts or parts that just don't go with the assembly.

There are also cases when peripherals such as the AC adapter are not available in large warehouse shops. Another major complaint about the ProForm XP 420 Razor Elliptical is the noise it makes, but this may well be due to an error in assembly. In addition, the machine is designed only for individuals with a light to medium build, as the unit tends to get wobbly during use.

This may be remedied by using the ProForm XP 420 Razor Elliptical over a hard surface such as a wooden or tiled floor rather than on a carpeted area. In any case, it is still not recommended for use by people whose weights are 200 pounds and up. The warranty that ProForm offers is 5 years for the frame and 90 days for parts and labor.

The workout display is LCD and is not backlit, so you can't really make use of it in dimly lit areas. There's a water bottle holder but no book holder, and at $400 you'll get a decent elliptical with only the most basic features. If you're a bit heavy-set, though, you may want to get a heftier and more stable unit.
