Hello Justin, If you are looking for best possible results, getting someone right up to the point of over training without going over will provide this. However most you work with will not be interested in making the workouts and recovery their life so it's not something to worry about. Consider this. For argument sake training 3x a week will give someone best and fastest results. For many the cost, time commitment and diet/recovery strategy would become a major part of their life. Let's say they stick this out for 60-90 days. You would have accomplished quite a bit with them. However it's probably a small moment in time for most. Now lets say you give them 1 session per week. Many more can afford this price point and even more then that, can fit it into their lifestyle. Also even with a sub par diet and recovery strategy 1 session is easily manageable to recover from for 99% of the population. Good chance if you do a great workout and a nice facility you can keep this clients for years. How much more will you get out of them over that extended period of time? My guess is most men will get to that 500lb leg press Logan mentioned!
