Stride Length

The stride length is the furthest distance between the two pedals of the elliptical in motion. A longer stride will give you more natural feeling, like a running type motion.
If you are over 5’4″ you may prefer a 20 inch or higher stride length and if you’re over 6 feet, you’ll definitely want a 20 inch stride or more. Ellipticals with a stride length of 18 to 20 inch are suitable for people under 5’4″.




Elliptical trainers have either a manual, motorized or electromagnetic resistance. Increasing resistance on the elliptical in your workouts will make the workout harder, causing you to burn more calories but be careful if you are a beginner.
Some elliptical trainers have heart rate programs that adjusts resistance based upon your heart rate.
