Here’s what it looks like you did;
Made a weight lifting logging app and charged a monthly subscription for it.
Used your users data to create an algorithm that culled the routine of your best performers, most likely defined by heaviest weight lifted.
Claimed that by following your algorithm your users could 2x the results of trainers; trainers here is defined as “people who train,” And not “people who are paid to train others.”
Cited 60 days as a window of success.
All of this, if it is as it appears, is massively misleading in an industry already known for snake oil.
Have you compensated for your users that had big numbers but approached it in an unhealthy way? For instance, how many of your user’s deadlift high numbers resulted in a hernias?
Additionally you say you have engineers and scientists working on hacking human performance. What about strength and conditioning coaches? What about athletes?
