Happy to give a testimonial. I have been a regular at Stephen’s Ashtanga class for last 4 years.  I find his 2 hour sessions both  physically challenging and relaxing at the same time.  I find the classes an excellent antidote to my hectic lifestyle, as well as being great for general fitness, strength and posture.  Stephen has a gentle & encouraging manner which makes the classes very enjoyable and helps people to progress at their own pace.  …..its great. Give it a go.
