First, ask the client “does this pain you feel lead to a decrease in your function?”  If the answer is yes then a medical route should be pursued. But, if the pain does not decrease the client’s function than it is up to the coach to identify the cause of the pain and work around it.

There are times when the anaerobic or lactic energy system needs to be improved for some particular clients. Specifically, anaerobic energy training is necessary for clients participating in intense sports like competitive functional fitness or football in which the work is highly demanding and success is dependent on how well adapted their glycolytic system is to the volume and workload. Anaerobic energy system training is not entirely necessary nor should it be a priority for those whose goals are only to be healthy. In any case, it is important to know how to build this energy system with the right person at the right time especially since a coach will eventually have clients who want to compete in some fashion in mixed modality fitness.
