FITT Principle of Training for clients

FITT Principle of Training

Getting the best out of a training program either for yourself or a client of yours is key. Considering your standard methods of training i.e. specificity, progression, overload and reversibility is something that is taken for granted. But sometimes when tailoring programs, we forget about the individuality of the client. This is where the FITT principle of training comes into play.

FITT Principle of Training

FITT principle of training (We’ll explain what the acronym stands for in a bit) should be thought of as the basic rules when tailoring a workout plan. Following these rules will ensure that your clients benefit as much as possible from the training plan.


Any method of training the body needs to rebuild and repair muscle fibres which have been torn during exercise it’s this rebuilding phase which makes muscles grow back bigger and stronger. The frequency of exercise is a fine line to put the body under enough stress, so it can adapt and grow but allowing enough time for rest and recovery.


This relates to the amount of effort given to an exercise, a whole session and the training plan that’s been created. Like frequency, there is a fine line between enough intensity to but the body/muscles under the stress required to grow but not too much that it becomes “overtraining”. Monitoring intensity can be used with percentages of 1 rep max weights, Heart rate monitoring and the RPE (Rate of Perceived Exertion) using a basic scale of 1-10.


Simply put this is how long you or the client is training for. Again, this can be determined by their experience levels but more importantly, it also depends on the actual physical time that you or the client has available to train. It can often be thought that longer is better. Train for too long in a session and once again you’re running the risk of overtraining.


This is what type of exercise are you going to use to achieve either your client’s goals or your own. There are two main types of training, Cardiovascular and Resistance. If your client has goals of half or full marathon running, then most of your training is going to focus on the cardio training function with the use of running making up the large part. However, to use the opposite example if you have a client that plays Rugby and is looking to increase strength to better their performance on the pitch then you’re going to be basing the training around resistance training with compound exercises with cardio as an accessory focus.

Listen to your Client

It’s key to remember that when programming for clients to listen to what they want. Their goals, family/work commitments as well as their lifestyle. Therefore, one training approach doesn’t fit for all. Discuss goals in depth with your clients, find out what they really want to achieve and use your skills as a trainer to help guide them to their desired outcome.
