We already learned that used stationary bikes are a fitness machine which is intended for home or gym usage. We also learned that used stationary bikes are excellent machines for cardio workout and that we have upright, recumbent, mini and folding used stationary bikes. We also learned what resistance mechanism they can have. Now some facts about treadmills, so you can form an opinion.

Treadmills are fitness machines which emulate effect of running or walking with difference that you are staying in one place. You can draw a parallel like stationary bike -> driving a real bicycle and treadmill -> running, walking. Treadmill gives us walking platform which consists of large belt and moving mechanism such as flywheel or electric motor. Motor moves belt allowing us to walk or run depending of the speed, which is controlled by a board computer.

Treadmills are excellent cardio machines and they have many advantages. Main thing is that treadmills give us reduced impact, which reduces shocks which further keeps knees, ankles, lower back and joints. Treadmill is indoor machine, so person can exercise regardless of what weather conditions are outside. As with used stationary bikes you can do other things while exercising, like watching TV. Depending on person factors such as weight and height, board computer can also calculate distance passed and amount of burned calories. Better treadmills even have heart rate monitors…

Treadmills also have few disadvantages. Walking on treadmill (or running) is easier then in real life. There are no bumps on the road and no wind resistance. This will give us 5% more strength and energy for further running.

Treadmill user can develop habit of wrong type running in outdoor situations.

Beginners can injure themselves by running on treadmills because of wrong feel of balance. Treadmills are large, such machine takes much of space indoor and usage of it can be monotonous comparing to the real running or walking.
