FITT Principle – Frequency is key to health and fitness success

When developing an exercise program there are many aspects to think about – what are you trying to achieve? What type of exercise should I do? How much effort is required?

There is an acronym in the sports and fitness world called the

FITT Principle.

Frequency – how often per week?

Intensity – how hard effort is needed?

Type – which specific exercise type can i use?

Time – How long do we need to do it for.

These principles help guide the decisions to make exercise and physical activity.

For example –

If your goal is to lose weight you can:

F – daily

I – moderate to hard pace

T – walking

T – 60mins per session

Or want to increase your run speed:

F – 3-5x/wk

I – hard intervals

T – running

T – 20-30mins

With all of these principles in mind – whats the most important to focus on?

Frequency is the key ingredient

You can have the best activity chosen, work super hard doing it, spending an hour or more at a time – but if the frequency isn’t regular – change will not happen.

Frequency is important in 2 main aspects:

Supra-compensation – Your body adapts to an activity or health change by being exposed to a stimulus (such as the effort involved in an exercise) then acutely adapts to handle the task – called supra compensation (making you fitter than before). If you expose your body to the exercise stimulus on a regular basis – you keep on improving in a stepped fashion.

If you only exercise once per week you will lose all of your gains.


The other and possibly most important aspect is that frequency helps to:

establish habits

It has been researched that it takes approximately 66 days to create a habit.

So if you were only starting your health journey by walking once per week – it will be very hard for the habit to become established.

Frequency is therefore the first and most important step:

  1. Get an activity happening on a regular basis,
  2. Stick at it to establish the habit, then
  3. Then focus on progressing as the exercise becomes too easy.

Give it a go – challenge yourself to do something regularly (daily if you can) for 66 days – when physical activity becomes a habit like eating or brushing your teeth – there is no stopping you!

 

Have fun in your health journey, and remember to stay true to yourself.
