Hey sorry to seem misleading — that isn't my intention.
I created an algorithm that trains you based on how top performers on Lift Log train themselves.
Top performers = highest percent change in total volume lifted from day 1. Sure, 60 days isn't a ton of data, but it is enough to show a difference.
Most people don't train properly and don't increase the difficulty of their exercises between workouts — following FitnessAI's algorithm (although it is incredibly naive) does indeed result in the performance boosts claimed. Try it out!
Regarding comparing to trainers — these are real trainers. I identified many trainers using lift log (on their clients phone) to keep track of training sessions.
