I'd like a training log. It would be nice to have a place to enter the exercises I perform, sets, reps and weight used (if applicable). Plus, it would make it easier for trainers to be able to keep track of progress. I'd also like to have a way to export the data to a spreadsheet such as Microsoft Access or Excel, so I can make a chart to more readily see my progress. Yes, I'm a geek. Lol.
