Too many times trainers are so interested in keeping their clients entertained that they lose sight of the end goal. They forget that it's about the program, not the workout. They are so concerned with doing the latest gimmicky thing to impress their customers that they forget about what is important. What's important is getting results, not being flashy.
Don't get me wrong, keeping your clients interested is definitely important, but it is also important to have a program in place that is both scalable and produces results.
