What is JuggernautAI?

JuggernautAI is a strength training app that generates individualized powerlifting and powerbuilding programs, built on periodization principles from coach Chad Wesley Smith's Juggernaut Training Systems. Users input their current maxes, training history, schedule, and recovery capacity, and the app builds a long-term plan around squat, bench, and deadlift, or a blended strength-and-bodybuilding approach. Its AI adjusts training weights, sets, and reps at the set-to-set, day-to-day, and week-to-week level based on logged performance and RPE (rate of perceived exertion), rather than relying on a fixed spreadsheet. The app includes a Meet Day Advisor for competition attempt selection, a 300+ exercise library with coaching cues, and a private community for peer feedback.
