The format I use has a clear and concise step process:
1- Identifying a clear goal/objective
2- Questionnaires/Tests to identify where the journey needs to start
3- Individualised diet protocol
4- Personalised stretching
5- Personalised exercise program that would be determined by the answers given in step 2
6- Lifestyle choices implementation to optimise steps and 5.
7- Retest once one cycle has been completed.

The content of the lessons:
Depending on what goal/objective is trying to be achieved, we may use a variety of things such as:
Stretching, lunging, squatting, bending, pushing, pulling, twisting, gait (which include, walking, jogging, running and sprinting), swiss ball exercises, body weigh exercises, "work-in" exercises that can easily be done with a mat on the floor, tai chi and many other things.
