AlterG M300 Anti-Gravity Treadmill

The AlterG M300 Anti-Gravity Treadmill is enormous, huge, expensive and something straight from the annals of a science fiction movie.  It looks like something you’d see on a space ship. However, it’s hardly just an impressive-looking piece of machinery.  It’s a rehab clinic’s dream.

The AlterG M300 Anti-Gravity Treadmill allows you to maintain fitness levels whilst nursing an injury. When you use it, you feel light as a feather due to its unique design and function. The AlterG M300 allows you to run or walk at a reduced body weight of up to 80 percent, while the differential air pressure technology assists by applying a comfortable lifting force to the body. By reducing the body weight, there is less impact on the muscles and joints, and people are able to move more naturally without pain, and keep up the cardio level usually associated with more strenuous exercise.


You simply step onto the treadmill and raise the enclosure to waist level to allow an air chamber to surround the lower part of the body. The controls are similar to regular treadmills with adjustable speed (0 mph to 18 mph) and incline levels (up to 15%). Once the start button is pressed, the AlterG measures your body weight, which can then be adjusted using the arrow keys, until a desired weight setting is achieved. As the body weight is adjusted, the air chamber inflates around the lower body and the air pressure “floats” your body upwards. The air pressure helps to make you feel secure and you are less likely to fall as you are supported laterally.
