DragonStrength is a digital strength training companion that uses evidence-based exercise science and physical therapy concepts to generate semi-random workouts that pull from an extensive library of exercises all hand-selected and curated by a licensed, practicing doctor of physical therapy to ensure that generative workouts are populated with the safest and most effective exercises, as determined by actual clinical trials. 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. All user data stays on device. - Designed to minimize taps - more time in the zone, less time on your phone - Data-driven weight & reps suggestions: No more mental math for progressive overload - Customizable profiles: configure by location - exercises that require unavailable equipment are excluded from selection
