What is Fitcheck?


FITCHECK is a bespoke blood testing service designed for Personal Trainers to use with their clients in order to offer them the most comprehensive results in the fastest time possible. The results are then automatically analyzed by the FITCHECK programme and presented to you in a simple and easy to integrate format in order to create bespoke nutritional and supplement client programmes.

Our aim is therefore to take the fear out blood testing for Personal Trainers by providing you with the information, knowledge and structure you need to help your clients achieve the best results possible.
