Overview
AlterG is an American brand of reduced-weight walking and running equipment, best known for its anti-gravity treadmill. The equipment uses air-pressure differences to create a reduced-loading environment inside the treadmill chamber, allowing users to walk or run at less than their full body weight. Its products are primarily used in rehabilitation, physical therapy, athletic training, and older-adult wellness, where controlled increases in lower-limb loading and exercise volume may be useful during recovery. Reliable public information is insufficient to confirm the founding year, founder, ownership structure, and complete product portfolio, so this entry limits itself to the brand’s established positioning and core use cases.
History
AlterG built its brand around reduced-weight walking and running technology. Its central approach is to use air-pressure control to reduce the effective load placed on a user while exercising on the treadmill, enabling rehabilitation patients and athletes to walk, jog, or run with less impact and lower loading. The anti-gravity treadmill has been marketed to rehabilitation facilities, physical-therapy centers, athletic-training facilities, and related health-service settings. Because verified public information is limited, this entry does not infer a specific founding year, technology-licensing history, management succession, ownership change, or product-generation timeline.
