More important than how big your hands are or how many hours you are immersed in water is how effective your mind is at conquering the challenges in the way of reaching your best performance. Swimming starts with the mind and mental training is a skill that can be learned by coaches and athletes. If you have time to attend a clinic by Dr. G, by all means attend. But, even if you have attended, excellence takes review and practice. Perfect Practice. Deep practice. This is the only tool of its kind. It will transform your swimming!
