I understand how you may feel reluctant to allow an external advisor to delve into the detail of your business. I have had other clients who felt the same way. But all of my other clients found the investment they made was repaid many times over both in their business and their own work life balance. To help you we have produced a free spreadsheet which will allow you to reflect on what you would like to achieve with your business and where you are at present. If you use the spreadsheet it will help you to identify if it would be beneficial to get an external advisor or if you are proceeding in the direction you want. Once you have completed the spreadsheet we will review the results with you if you want at no cost to you.
Well, let‘s take a look at your situation. What level are your athletes or clients at? New athletes or clients probably would not benefit from percentages as much as more advanced clients, as they need to learn how to perform the lift correctly first and foremost. Second, a new client will adapt to the exercise so fast that by the next time you perform the exercise, their 1 rep max may be out of date and thus their percentages would be incorrect (if they used to bench 100lbs, but after 2 workouts they can bench 110lbs, that 60% you have them working out as now too low to cause the adaptation you are looking for).
