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.
