Personal Training Tips

My position at Fitness 360 in regards to Nutritional Supplements is very simple- It is outside the defined scope of practice of a fitness professional to recommend, prescribe, sell, or supply nutritional supplements to clients.  Recommending supplements without possessing the necessary qualifications can place the client's health at risk and possibly expose the fitness professional to disciplinary action and litigation.  There are also potential issues with interactions between supplements and other drugs clients may be taking.  Supplements aren't regulated by the FDA, so there's no guarantee of purity, strength or interactions with other drugs.  A personal trainer's main scope of practice is to help people improve their health and fitness through exercise and behavior change. Trainer's are not qualified to go beyond educating clients in nutrition matters. 

So remember a trainer can educate you on nutrition but make sure you consult a registered dietitian before you start a particular supplement or a new diet program.
