Elliptical Trainer Vs. Running
Running and using an elliptical trainer are very similar forms of exercise with a few key differences. The elliptical is designed to adjust the impact on the body. Running is a very traditional form of exercise that has its pros and cons. The two exercises have somewhat similar effects on cardio health but vary greatly in their impact on the body. Combining the two activities can produce custom results for people with concerns relating to either one.

Elliptical
-
The elliptical machine was invented to simulate the effort and cardio stress of running without the impact. The elliptical machine is designed to follow the running motion, and at the end of the forward stride the machine carries your foot around in an elliptical motion. This unique motion allows the person using the machine to also be able to "run" backward, working the leg muscles in a different way. Some people feel safer going backward on an elliptical as their feet are constantly supported as thy move. The one negative of the elliptical machine is that it is stationary.
Running
-
Running is one of the most ancient forms of exercise. Today, millions of people worldwide run to stay in shape. Running can elevate and maintain the heart rate to a level that improves cardiac function, according to TheRunnersGuide.com. Running also can provide mental clarity and improved mood. Running can be done out on the trail, the street or on a treadmill allowing you to vary the mental stimulation while getting a workout.

Cardio
-
Both running and using an elliptical provide a good cardio workout as they are a similar motion that can be done at similar intensities. The elliptical machine allows you to increase the resistance, making each step more difficult. When you try to maintain pace, your heart rate rises. When running, to increase the cardio stress, you can run hills to increase resistance and heart rate. Sprints can be done while running or on the elliptical to increase the cardio load.
Imapct
-
Running produces far more impact stress on your body. The elliptical provides almost no impact stress as that is its primary design function. The medical community has not come to a consensus on whether or not impact is good or bad. Some impact encourages bone density. Every time the body hits the ground, structures are broken or weakened; when the body repairs these minute injuries, that part becomes stronger. This can be good in moderation, but too much stress could begin to break the body down before it can repair itself.
Cross Training
-
Running a couple days a week and using the elliptical machine other days is considered cross training. Doing both can be a great way to keep up cardio capacity without overdoing impact stress on the body.
