Answer:
People who hit the gym regularly to either lose weight or gain muscle need someone to supervise their workout. This is where a personal trainer comes in. You will design a training program for your client to follow. If he fails to follow the program, then the problem is with him. In other words, you will devise a workout plan, let the client do all the dirty work and lifting, and get paid regardless if he follows the plan to the letter or not.
