Startup Idea: Workout Tracker and Progress Visualizer Software

Startup idea to develop an affordable, user-friendly software that converts workout data from a spreadsheet into a graph. The tool should be capable of tracking different parameters such as exercises performed, rep goals, and weights lifted. It should facilitate easy input of values and offer comprehensive progress visualization.

I'm actually very glad that this came back up, as I recently had something that software could help solve. I recently started working out and since then I have been keeping a spreadsheet of information such as the lifting exercises I'm doing, if I completed my rep goal, and the weight I am currently lifting with a note when i increase the weight. I would love to see a piece of software that could turn this spreadsheet into a graph of some sort so I can look over my progress at the end of the year. While there is some software that does this, it is either outrageously expensive, way too complicated, or only does part of what I'd need it to do. A low cost and user friendly alternative would be great. Or maybe a program where you simply input the values into it and it keeps track.
