“Our ethos became and still is today — don't make me think. Get that person in there, they press play, they do the workout, and if we can do that three times a week that is really what ladders up to retention.”

Don't make me think — remove all friction between the user and the core retention action

Ladder's product philosophy borrows from Steve Krug: every decision that requires thinking is friction between the user and the result that drives retention. The entire app is architected so pressing play is the only required user decision. Once you have identified your retention north star (results to consistency to three workouts per week), the product's sole job is to make that action effortless — not to give the user more choices, features, or things to think about. Complexity is the enemy of habit formation.
