Please be aware that Shotokan Karate is a demanding physical sport. It is the responsibility of the student or the students parents/guardian to ensure that they are fit enough to undertake the training. The instructors of Shikata Shotokan Karate are not qualified medical practitioners and if there is any doubt regarding the students fitness to take part then those concerns must be addressed to a doctor. If advised by a doctor not to train then that student should not train. If any approach is made to an instructor regarding an injury or disability that might make training a problem then the instructor will advise the student that until such time as stated that it is safe to train that student should not train. All medical questions should be addressed to qualified medical personnel and NOT to a club instructor. Having said all that it's a great way to keep fit and healthy.
