Hi team, I use Whoop for strength training. I work as a product manager in mobile apps, so this comes more from a colleague than from a user.
Today I can describe a workout in free text in the chat and Whoop builds the card from it, with no manual exercise selection. That already removes a lot of friction. The next step would be capturing the same information during the session instead of after it. I say the exercise and the weight out loud as I go, or repeat what my trainer tells me, and Whoop builds the card from the audio. Nothing to reconstruct from memory at the end.
The band has no microphone, so this would rely on the phone and only work for people who bring it to the gym. Still a useful first step, and maybe an argument for a small microphone on a future band.
