Yup, this ties in with my last Training post. My trainer used Trainerize (which he pays for) that tracked all my workouts, and let me enter and see my stats. I won’t have access to that come January.
Notepad - nope. My handwriting is terrible, especially at the gym. Sometimes I can’t even read what I wrote.
Spreadsheet (e.g. Google Sheets) - Probably not. Too much prep work for each workout. I could probably script something up with macros (not THOSE macros, lol), but I’d rather not reinvent the wheel.
Apps - So many to choose from. What do you all use? I’m okay with paid apps, too.
