Stop guessing. Start progressing. Progressive overload is the only way to get stronger โ€” Milo of Croton proved it 2,500 years ago carrying a calf until it became a bull. The principle hasn't changed. But your app should give you more than one way to do it. Croton gives you 4 different progression strategies โ€” not just one. Whether you're adding weight every session, every week, or using double progression for hypertrophy, Croton adapts to how YOU want to train. FEATURES - 4 Progression Strategies โ€” Linear, double progression, AMRAP-based, or manual - Automatic weight increases โ€” Set your rules, we handle the math - Smart deload logic โ€” Automatic deloads when you stall - Workout builder โ€” Create any workout with 100+ exercises - Session tracking โ€” Log sets with one tap - Plate calculator โ€” Know exactly which plates to load - Rest timer โ€” Customizable between sets BUILT FOR LIFTERS BEYOND LINEAR PROGRESSION Loved StrongLifts but hit a wall? Dealing with an injury or joint issues? Your body doesn't progress in a straight line โ€” your app shouldn't force you to. Croton lets you choose how you progress, not the other way around.
