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a new client will adapt to the exercise so fast that by the next time you perform the exercise, their 1 rep max may be out of date and thus their percentages would be incorrect (if they used to bench 100lbs, but after 2 workouts they can bench 110lbs, that 60% you have them working out as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).
Electronic medical record software which some refer to it as EHR (Electronic Health Records) is a hospital clinical database management system called DMS. This software aims at improving the patient care by providing efficiency, fast retrieval of data, increased productivity and revenue and reduced running costs. An EHR solution lies at the heart of any computerized health information DMS that should essentially provide high quality patient care for all intents and purposes, reducing medical errors, delays and oversights in patient treatment.
