About Ace Performance

Dan Osman BSc (Hons), Dip. ISSN, CISSN, ASCC

An experienced personal trainer, strength and conditioning coach, CISSN sport and exercise nutritionist, and PhD Nutrition sponsored athlete.

“Growing up I wasn’t very sporty or athletic, and as a teenager I was never comfortable in my own skin and in all honesty carried a little too much puppy fat with the low self-esteem, and confidence that went with it. Somewhere between 16 and 17 I discovered weight training and focused more on my nutrition, which brought about a new self-confidence, and the rest as they say is history.

After a spell of developing a passion for health and fitness I was introduced to Brazilian Jiu-Jitsu (BJJ), Mixed Martial Arts (MMA) and Muay Thai - I was hooked! I can proudly say that the old school methods of training are still alive and well today and with reference to BJJ and MMA - Sink or swim! Being constantly paired with, and quite frankly manhandled by stronger, heavier and more experienced guys made me long to be stronger, faster and more powerful to keep up with them, which is where my passion for strength, conditioning and nutrition evolved”.

Dan is focused about getting results for his clients and combines a down to earth approach, with an unprecedented and asserting passion for fitness, health, nutrition and performance. Empowerment are key methods of Dan’s approach to coaching, giving his clients the tools they need to achieve real, tangible, life changing results. Because of this Dan ‘lives the life’ and is as serious about his own training as he is with his clients, continually improving his methods of coaching and training through education and self development. Dan is a first class BSc in Sports Studies (Hons.) graduate as well as being certified with the International Society of Sports Nutritionists (CISSN) and a UKSCA (ASCC) as an accredited Strength and Conditioning coach. He has built on this foundation by working with a range of professional athletes and clients, from his postgraduate appointment at Saracens Premiership Rugby Union Club in preparing the senior squad for their 2008-2009 season, followed by his post within the University of Hertfordshire’s Performance Team working with talented, amateur and elite level athletes, included within sports initiatives such as the national Talented Athlete Scholarship Scheme (TASS), Elite Athlete Support Programme (EASP), Norwich City Football Development Centre., England Women’s FA, Batchwood Tennis High Performance Centre, Gosling Tennis High Performance Centre, Badminton England and Mavericks Netball Club.

Dan has nearly 12 years experience in the industry and now continues to work within the East region of the country, predominantly within Essex. He worked with a wide range of clientele from those who wish to transform bodies and improve their health, fitness levels, recover from injury, lifestyle, to physique, TASS, MMA and powerlifting athletes, to name a few. Furthermore, Dan has been a consultant for the ASA’s diving talent program and an England Netball London & South-East Academy Coach and Coach Educator. Dan recognizes that every client is an individual, and knows because of this every client requires a bespoke nutritional and training program to achieve their goals.
