Exactly this. Using a phone/website/app while I'm lifting weights in the gym is the last thing I want to do. So, I use pen-and-paper and copy over to Google Sheets weekly. That way I have the raw historical data: I can track progress, derive metrics, and create graphs with ease. But that's not to say I don't want a better solution! Workout logging is primarily an exercise (pun not intended) in intense user experience design. The designer must understand the task context. There's one killer input modality in my mind -- an Apple Watch. I have no issue wearing a watch while I'm working out. And it'd be fantastic if an app could: - Track my daily exercise ordering (i.e. it knows what I'm supposed to do next) - Show my rep/weight history for the current exercise and allow input of results after sets - Monitor and record my HR throughout my workout and estimate my rest intervals/vibrate when my rest interval is up - Offer alternative exercises when requested - Etc. There's so much you could do with a watch as the primary mode of input. The watch is what you use in the gym. And the computer/tablet is what you use for analysis later. If someone were to execute this properly, I'd be all over it.
