Personal Trainer in Aylesbury

Maximize your potential whether it’s fat loss, muscle growth, or general fitness

These four principles of fitness training are applicable to individuals exercising at low to moderate training levels and may be used to establish guidelines for both cardiorespiratory and resistance training.

The FITT principle is used to guide the development of unique and bespoke fitness plans that cater for an individual’s specific needs.

F.I.T.T. stands for frequency, intensity, time, and type of exercise.

  • Frequency - decide how often to train.
  • Intensity - choose how hard to train.
  • Time - decide for how long to train.
  • Type - decide which methods of training to use.

"I chose James as my PT because he seemed to understand intuitively about where I wanted to go with my training.
Training with James was always fun and encouraging yet pushed me to the maximum I had on the day.
The variation of each session was great and acknowledgement of my progress.
I would recommend James to new clients and have encouraged my daughter and friends to partake in his classes and PT sessions.
My goals over the 7 years I trained with him varied from fitting into my wedding dress to partaking in cycling challenges overseas and in the U.K. And with James never ending encouragement I cycled 450kms in Africa in 2015 and also Vietnam and Cambodia in 2016, raising money for Cancer charities. He also helped arrange a spinathon to help raise money for the charity. He has an enormous amount of generosity of spirit towards his clients and is happy to help in whatever way he can to help each individual achieve their goals.”

  • positive review  Every session with James is something to look forward to. Not only do you get an amazing workout, but the whole feel of the session is chilled and fun. You can certainly tell that James knows what he is talking about, and he is great at explaining what you are doing and why. I like that James is able to adapt to my needs and ability, but also makes sure I work to the best of my capabilities! The gym area is very well equipped and is a comfortable and well designed space. I would certainly recommend Simply Fitt if you are looking for a PT.w

Really please with the results!

  • 5 star review  Had my first session today with James, and I absolutely loved it! Such a great feeling, felt so comfortable and relaxed. Was worked hard and at all times was reminded to let James and Ashton know if I felt any pain or faintness. So professional and friendly, really looking forward to the future being fit and healthy. So looking forward to my next session, would highly recommend! Many thanks!
