AlterG Anti-Gravity Treadmill
Medfit offers its clients the unique technological application of the AlterG® Anti-Gravity Treadmill®. AlterG’s unique unweighting technology reduces the impact of walking or running, allowing your body to experience the sensation of being able to move more freely. This will optimise joint and tissue health, in ways you would be unable to do ‘on land’ or on a regular treadmill.
AlterG uses technology patented by NASA, called ‘Differential Air Pressure’ (DAP) technology, invented whilst studying the effects of zero gravity on astronauts. With the AlterG Treadmill, you will be able to:
- Precise unweighting allows you to walk or run between 20 and 100 percent of your body weight
- Easily select your unweighted bodyweight where movement becomes more comfortable or painfree
- Lower the impact on your joints and muscles during exercise
- Fun and easy to use, run or walk like you’re on the moon!

What Our Patients Say
Dean Doyle2025-04-22Trustindex verifies that the original source of the review is Google. After rupturing my ACL, I was sent to Stephen to help with my rehab to get me back doing sport without getting surgery. The help I got was second to none and I returned to sport within 6 months of the injury. A year after my injury, I decided to get surgery and Stephen was able to help me prepare for the surgery and help get me back to full training earlier than anticipated. I was fully prepared for every step of the journey thanks to Stephen and he made what I needed to do at each stage very clear to me which helped hugely with the rehab. Stephen was able to show me the progress I made throughout the entire rehab process which helped add an extra incentive.

I was given exercises which were tailored to suit me and Stephen’s technical knowledge and attention to detail was very effective. I couldn’t recommend the place more!

I tried various approaches but with no success. Medfit was recommended to me and I booked an appointment with Stephen Armstrong. At the first appointment he carried out a comprehensive assessment and devised a plan with me to address the issue. Within a few weeks I improved dramatically. In total, I had 5 appointments with Stephen and am now pain free. Stephen’s empowering approach is fantastic. Thank you Stephen. Pat Godfrey2023-11-07Trustindex verifies that the original source of the review is Google. Last year I had open heart surgery to replace my aortic valve following which I had many serious infections. This impacted on my fitness levels and my self confidence to partake in strenuous physical activity. Some months ago I committed to join some of my fellow hill walking club members for a hill walking holiday to Greece in September. The big challenge was to climb Mount Olympus, Greece's highest mountain which involved staying in mountain huts for two nights. To prepare for this challenge I enrolled for a three months exercise programme with Med Fit. I was fortunate to have had Alana Doran as my one to one adviser. Alana outlined a fitness programme for me which was reviewed regularly. During our weekly one to one class Alana, in addition to attending to my general fitness levels also focused on the various body parts relevant to my forthcoming hill walking holiday. The good news is that I climbed Mount Olympus, and also partook in some other less demanding climbs without any difficulty. I thank Alana for her professional assistance to me and also for enabling me to have the confidence to take on the challenge. I also acknowledge her for being so pleasant and easy to communicate with.
