Is treadmill better or running on the roads?

Running on a treadmill is much easier as there is no wind force blowing against you. Treadmills also have a propelling force, which makes the foot come in front of the other. Walking or jogging on treadmills is a boring job. On a road, you have to change according to the surface and this helps in developing many muscles and tendons in the body. While running on roads, the surface is inclined or sloped and there are potholes, grass, soft mud, hard surface etc. These help in building different muscles. The main beneficial factor while running outdoors is that the oxygen levels in the air is high while indoors it is stuffy. Natural environment is the best to jog and exercise as exercise is meant to be done outdoors. Treadmills can be used as an alternate when the weather is not good enough to jog outdoors. If you don't have much time and you are in a hurry, then you can workout on a treadmill. Treadmill is an alternative to jogging but jogging outdoors is always the best.
