Smarter suggested metrics use previous workouts, selected training mode, and configurable progression goal to calculate the optimal weight, set, and rep combinations to achieve progressive overload for each exercise, at a pace you decide. An integrated workout log provides a place to save completed workouts for future reference as well as a living data set that populates a variety of graphs and figures for easily tracking gains and identifying training plateaus. Differentiating features: - Point-based generative workouts: YOU control the algorithm - as random as you need it to be (or not at all!) - Curated, customizable exercise library of >240 unique entries, regularly updated by a licensed physical therapist - No more pre-planning workouts: configure a full, custom routine as you walk into the gym, in as few as 2 taps - Privacy-minded: NO user accounts, NO AI features, NO network dependency.
