Standing up is insufficient. Translocation of the trunk is what you need.

Of course if you do squats with your Macbook then it's alright.

But yeah, we need to hone the marketing. Any particular areas that are fixable with copy changes or are the required changes bigger than that?

The aspect of "time" relates to productivity. I consider this a motivational tool using game-ification and social media. The reason I love interval training for running and getting into shape is that it gives me a tangible sense of progression. When I am able, I can move on to the next tier of my running program, which is tougher than the former. "Accessible", "Tangible progress", "Mobility", "Social", "Motivitational".

I wouldn't equate doing the FitFu exercises with working out in the gym. Sure, if you do the same exercises there, but I assume that working out in the gym is more intense. The exercises don't strike me as cardio- nor weight/strength-heavy.

You could promote it as a Wii Fit for iOS or a mobile version at that. Break down what makes Wii Fit entertaining and popular (to those who do) and try to apply it to your product.

The main use-case is to ease people into regular exercise, but even though I'm a fairly serious gym-goer myself I find that doing a few reps here and there throughout the day is really helpful to keep my mind refreshed.

What happens in practice (if the testers are anything to go by) is that they start pushing themselves further and further so actually this break time kinda becomes productive in its own right.

Something like that!

Hopefully we'll get better with the marketing with time as we receive feedback from a wider audience

When I replied earlier I missed the productivity bit.

That was just one point that came out of the TC chat, but arguably it makes sense when you think about it. Those little bits of exercise now and then really do refresh you and help with stress... There's a lot of discussion in general on HN about the benefits of exercise.

Or work on not getting that feeling as often. Works for me :-)
