Alter-G Treadmill
What is an Alter-G Treadmill?
An Alter-G treadmill is a specialised rehabilitation treadmill that uses air-pressure technology to reduce how much of your body weight you run or walk on. By wearing a comfortable inflatable waist-high support, the treadmill can unload up to 80% of your body weight, allowing you to move with far less stress on your joints, muscles and bones — while still maintaining a natural walking or running pattern.
In simple terms 👉 You can move earlier, with less pain and more control.

What are the benefits of using an Alter-G?
Reduced impact | Lower body weight = less load through hips, knees, ankles and feet. Ideal when impact is the problem, not movement itself.
Earlier return to running or walking | Athletes and active people can reintroduce running sooner without overloading healing tissues.
Precise load control | Body weight can be adjusted in 1% increments, allowing very gradual, evidence-based progressions.
Maintains fitness during rehab | You can keep cardiovascular fitness, running mechanics and confidence while injured.
Pain-free movement | Many people can move comfortably when normal walking or running would otherwise be painful.
Who is the Alter-G useful for?
- Stress fractures and bone stress injuries
- Post-surgical rehabilitation
- Tendon injuries (Achilles, patellar, hamstring)
- Knee, hip or ankle injuries
- Arthritis or joint pain
- Return-to-run programs
- Athletes needing controlled load progression
Alter-G at The Sports Physio Clinic.
Using an Alter-G properly is not just hopping on and jogging!
At The Sports Physio Clinic our sessions:
- are physiotherapist-guided & supervised
- have individualised load, speed and planned progressions
- are integrated into a complete rehab plan – not used in isolation
- are planned based on injury type, symptoms and recovery stage
This means safer progression, better outcomes & fewer setbacks.

Book an Alter-G Treadmill session today if you are:
- Frustrated by pain with normal walking or running
- Stuck between rest and full impact training
- Returning from injury and want to do it properly
👉 The Alter-G can bridge the gap.
Used at the right time, it helps you stay active, build confidence, and return to full training sooner — without rushing recovery.
