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 manual, motorized, or electromagnetic resistance. Increasing the resistance on your elliptical during workouts will make the exercise more challenging, leading to a higher calorie burn. However, if you’re a beginner, proceed with caution. Some elliptical trainers feature heart rate programs that adjust the resistance based on your heart rate.
