Agreed. I would recommend bringing on board someone who's worked as a strength coach, or has some sort of expertise around long-term training regimens. Specifically, "muscle confusion" isn't a real thing. Have you spoken with any high-level athletes?

And it's easy to see if you're plateauing. That's when your performance plateaus. If there's any published research showing that this device has predictive power, that's a different matter. But I imagine that tracking cortisol/testosterone levels over the long term, plus the immediate hormonal response to an exercise stimulus (over the 0-48 hour window), would be much more effective than any sort of impedance-based approach. Plateaus and overtraining are more hormonal than muscular.
