I have trained under john for 2 months and he has guided me with exercises according to my capacity  I suffer from Exercise Induced Asthma and he made sure he would advise me exercise based on my capacity that I don't get an asthmatic attack The exercise he has recommended has helped me with increasing my stamina and I have lost weight as well I would be joining him again in future without thinking and would recommend my friends to train under him - Meenal
