With regards to all forms of exercise if you have any doubt about your level of health and fitness it is advisable to consult your GP prior to the commencement of any new fitness plan. The instructor must be informed of any injuries, handicaps or medical problems prior to joining the classes. Tina Olliver/Yoga-etc cannot accept responsibility for personal injury whilst participating in a class if a) You have been advised against exercise on the basis of a pre-existing health condition by your GP.b) You fail to observe the techniques & instructions given regarding safety. I acknowledge that I exercise at my own risk. *
