Back to Action is a new exercise application specifically designed for people with Ankylosing Spondylitis (AS). It has been created by physiotherapists working with NASS and the exercise therapists and doctors who treat military personnel with AS at Headley Court. It uses the most up-to-date knowledge from the fields of physiotherapy and sports medicine.

We have tried to make the application as clear, straightforward and enjoyable as possible, so that you can use it in a gym or at home as part of your daily routine.

The application covers mobility, cardiovascular, strength, flexibility and breathing exercises with additional information on other classes and sport as well as information about AS for gym personnel.


The National Ankylosing Spondylitis Society (NASS) is the only registered charity dedicated to the needs of people affected by ankylosing spondylitis (AS) in the UK.

NASS provides information and advice and campaigns to raise awareness of AS and the needs of people with AS. NASS has a network of branches in the UK, providing regular exercise and hydrotherapy sessions supervised by NHS physiotherapists. We also actively encourage our members to take part in research into the causes, genetics and management of AS by recruiting volunteers for various research projects around the UK.

Exercises for AS: how to keep supple

This is an excellent app with informative videos and instructions from trained physiotherapists. Even better, the NASS charity supports groups around the UK to meet and do exercises together. Put in a good word for them and encourage them to produce an ipad version - please!

Good for generally bad backs too!!

I have intermittent problems in the lower back and there's some brilliant exercise info and videos in this app that have really helped! Not just for people with AS :-)
