These treadmills are often considered to be the most realistic because they offer varied resistance that can be adjusted to match your speed. Additionally, air resistance treadmills tend to be very quiet.

Water Resistance

Water-resistance zero gravity treadmills use water to create resistance. The water is typically stored in a tank located at the front of the treadmill, and as you run, the water is pumped through hoses to create resistance. These treadmills are often considered to be more challenging than air resistance treadmills because they provide a constant level of resistance. Additionally, water-resistance treadmills are usually very quiet.


Land-based zero gravity treadmills use a belt to create resistance. The belt is typically located at the front of the treadmill, and as you run, the belt slides against you, providing resistance. These treadmills are often considered to be the most challenging ones.
