In over 16 years of boxing experience - as an England amateur International and now as a World No. 1 ranked professional - I’ve travelled the globe and worked with some of the leading coaches, trainers, conditioners and fitness instructors my sport has to offer. However, seldom have I discovered an individual as well-rounded, astute and knowledgeable as Jamie ‘Jazz’ Sawyer, or, ‘Mr Perfect’ as he’s known in the industry. ‘Perfect’ by name and perfect by nature, Jamie’s thirst for utter perfection in every aspect of his game puts many of his rivals to shame. Also, I use the term ‘rivals’ loosely. After all, I’ve worked with some of the best trainers America, Russia and Cuba can boast, and Jamie remains comfortably in a league of his own. In actual fact, he’s playing a different sport altogether! Jamie is the Miles Davis of his field - unquestionably miles ahead of the rest. Whether it be strength training, Pilates, Boxing, Plyometrics, Wrestling, Yoga or even simply a nutritional program, Jamie is not only an authority in each field, but is up to date with all the world’s cutting edge research, and incorporates these specialist training methods into my daily sessions. The saying goes, ‘The proof of the pudding is in the eating’. Well since being privileged enough to work with Jamie, not only have I scored spectacular K.O after spectacular K.O, my strength has improved by 42%, and my running and agility drills have been catapulted to a new stratosphere. The proof is, indeed, in the pudding, and Jamie Sawyer invented the recipe! David D. Haye AKA The Hayemaker

Cathy Brown is the current holder of The British and European Professional Flyweight Titles, and is currently ranked number 3 in the world in her weight category. She was the second female to receive her professional license in the UK and the first ever female in the UK to win a Professional British title. She has sailed across the Atlantic in an attempt to break the World record and ran 120k in the Verdon Canyon, France. She is currently preparing to race huskies across the Antarctic next year. "Since training with Jamie, I have become a much stronger fighter. Due to his meticulous sports specific programs, I was able to compete at a World Class level"

My name is Robert Lloyd-Taylor. I am a professional boxer fighting out of West London and currently ranked 8th in the British Welterweight division; I am hoping to box for a title in coming months. I have been boxing under Hayemaker promotions for the past year and a half, in which time I met strength & conditioning coach Jamie Sawyer. I have found myself going from strength to strength with the training techniques Jamie has applied. With a scientific approach to my training, I have felt an increase in energy levels, power and endurance. Training sessions are always different and Jamie keeps me motivated, which is why I would recommend his technique to any athlete or keep fitter.
