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a new client will adapt to the exercise so fast that by the next time you perform the exercise, their 1 rep max may be out of date and thus their percentages would be incorrect (if they used to bench 100lbs, but after 2 workouts they can bench 110lbs, that 60% you have them working out as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 health records come in two categories; client-server or web-based. Web-based EMR offers a wide range of solutions including cloud-computing products, free online systems, shareware systems, open source systems etc while client-server is the traditional choice for many office based and long-term care physicians since it is solid, housed and maintained on the owner‘s server. Most client-server EMR Software packages are large and well-known.
