Move freely.
Recover safely.
Train without limits.
Originally developed by NASA. Now available at Physio Fitness Dorset.
The AlterG Anti-Gravity Treadmill allows you to walk, run, and train with significantly reduced impact on your joints — making it possible to exercise earlier in recovery, with less pain and more confidence.
Using calibrated differential air pressure, the AlterG lifts and supports your body while you move on the treadmill. You wear specially designed neoprene shorts, zip into an airtight chamber, and your body weight is reduced from 100% down to as little as 20% — in precise 1% increments. The result is a near-weightless feeling that reduces strain on joints and muscles, allowing you to move more naturally without fear of pain or reinjury.
At Physio Fitness, the AlterG is always used as part of a wider treatment plan, supervised by a qualified therapist who guides your set-up, monitors your gait, and adjusts your programme as you progress.
How the AlterG helps you recover and perform
- Earlier rehabilitation — begin loading and moving sooner than traditional rehab allows
- Pain-free movement — exercise without overloading healing tissues or painful joints
- Real-time gait analytics — live feedback on how you’re walking or running to improve technique and symmetry
- Rebuilds strength and endurance — without the impact that would set recovery back
- Restores confidence — patients feel safer, stronger, and more optimistic from the very first session
- Performance training — train harder and longer with reduced strain, ideal for athletes building back to full fitness
How does the technology work?
The AlterG uses NASA-derived differential air pressure technology. An airtight chamber surrounds the lower half of your body and inflates to create uplift — effectively reducing the gravitational load on your legs and joints. Body weight support is adjustable in 1% increments from 100% down to 20%, giving your clinician precise control over the load placed on healing tissues at every stage of recovery.
Is the AlterG right for you?
The AlterG is suitable for a wide range of patients, from those in the early stages of recovery to competitive athletes returning to full training:
- Lower body injuries and surgery recovery
Build strength and mobility safely after ACL reconstruction, joint replacements, Achilles injuries, stress fractures, and more. - Neurological conditions
Improve walking patterns, endurance, and balance in conditions such as stroke, MS, Parkinson’s, and neuropathy — in a supported, safe environment. - Age-related mobility and confidence
Help older adults maintain strength and cardiovascular fitness, regain confidence on their feet, and stay active — with minimal impact on joints. - Athletic training and injury prevention
Train harder, faster, and longer without the strain. Ideal for runners, footballers, and athletes returning from injury or building endurance.

- Your clinician will set your body weight support level based on your condition and goals
- You’ll walk or run on the treadmill while your gait is monitored in real time
