Never offer medical advice. Do not try to diagnose, treat or offer your opinion about any medical condition or disease. If the client has an injury or illness that might adversely affect his progress in an exercise program, it is your responsibility to refer her to a physician.
Never overestimate your knowledge or abilities. You gain nothing by doing so and risk injury to the client. If you need to, get a second opinion from a trusted mentor or a fellow personal trainer.
Do not dispense nutritional advice unless you’re trained to do so. This means either earning a specific certification or acquiring software that will allow you to offer more personalized nutritional advice without crossing the line. Most nutritional programs available in the market today were created by nutritionists and dietitians and are administered under a “template” design, ensuring that you work within pre-determined guidelines.
Avoid private interactions with clients, such as dating or developing personal relationships outside your fitness training.
