I worked out with Gyles on personal training for 2 months. I can only strongly recommend him. Gyles is a very competent and gifted trainer and person.
The lessons are always fitted to the need, various and highly effective !
Training with him helped me enormously to stand the busy and difficult life : it gave me strength and relieved the stress.
I'm a big fan of his method and wish every lucky person working with him lots of fun.
