Air walkers are characterised by the fact that they provide no impact to the joints of the body. Your feet glide back and forth on stationary paddles in an arcing motion. Performing a workout on the air walker can help people who have issues like arthritis or who are recovering from knee surgery.
Muscle endurance is an important factor with jobs that involve a repetitive motion for long periods of time. An example of this would be working for a delivery company. You are always walking and picking up packages. Training on an air walker can keep your muscle endurance at a high level and translate into your daily job.
When you are exercising, it is a good idea to monitor your progress to maintain fitness levels. Some air walkers come equipped with a digital screen on them. You can look at this screen and find out your distance, time and caloric expenditure. There are some that even have built-in heart rate monitors as well.
When you are working out on an air walker, you are burning calories which leads to weight loss. But another way they help keep you fit is when you leave the machine. After an intense workout such as an interval routine, your body's metabolism is going to be increased for hours after you have finished. This is called the Excess Post-exercise Oxygen Consumption (EPOC).
Air walker machines also have another added benefit. They have handles that sway back and forth in unison when you move your legs. This will keep your upper body and lower body fit simultaneously.
