Air walkers from Meerut Gym and Gymnastic Works work muscles in both the arms and legs. Most Air Walkers from Marino come with ski poles that you can use to exercise by pushing or pulling with your knees. Your abdominal muscles act as stabilising muscles and get a moderate workout while you maintain an upright stance on the machine. You just have to hold the handlebars and jump one foot at a time onto the flat foot pedals. When holding your hands on the handle bars, step one leg forward at the same time as you move the other backward. Since your heart will have to work harder to pump blood into your arms and legs, your heart rate will rise.
