I use fitnessbuilder.com Its a website, but also an app, so I can use it anywhere.
I like the overall functionality. Its very easy to write, email and print programs. It has a lot of exercises, programs and the ability to photograph, write a description and add your own exercises. You can also invite your clients to join (for a fee) and you can track their progress. I like that I track my clients progress myself during our sessions and then make notes right on the session or on the clients profile.
The downside is that I still find numberous exercises that are not listed, that I then have to add myself. I wish there were more baseline stats that you could add, like a mile test, squat test, push-up test, etc. I also wish that there were more modifications for certain exercises listed.
Great question. The best source to write fitness programs is using what I learned from NSCA’s CSCS certification. Having a solid understanding with structural exercises(lat pulldowns, shoulder press, leg press) as compared to non structural(calf raises, tricep pressdowns) and how the larger muscles of the body such as Lat’s, quads, are essential as they require more ATP, then the smaller non structural exercises.
It always is fundamental to analyze the initial history taken, understand and medical or complicated issues and then examine their workout history/diet to begin to design exercises.
This is the science we should use not relying on a computer program. Thinking and justifying to ourselves as fitness professionals is vital then relying on a computer.
“Understand the science behind the movement” is VITAL!!
