Real humans. Invisible technology.

Kai is not one single person. Kai is the combination of experts in fitness, diet, mindfulness, and accountability. Our technology ensures that Kai never loses track of your progress, so you don't either.


Daily interaction. Daily progress.

Lasting results and life-long habits come from relationship. Kai gives you a personalized plan and sets the pace that's right for you. You maintain control of your schedule and your life. Kai works on your time.


No judgement. No shame.

Kai will never make you feel bad about your fitness journey. Kai won't make you take before/after photos. Kai won't show you a photo of a ridiculously fit person (unless it's part of a meme).


Kai helps you make fitness a part of your life.


The fitness world is overwhelming.
