Training OP

Training Overload Progression (TrainingOP) is a strength and hypertrophy app that helps you progress steadily, increase training density and avoid injuries or overtraining. It provides a structured, long-term system that automatically adjusts reps, weights and microcycle length based on your real performance, so you can focus on training instead of spreadsheets. Whether you are a beginner or experienced lifter, TrainingOP is built for natural, sustainable progress without unnecessary plateaus or exhaustion. Key features: • Per-exercise progression – An exercise is counted as successful as soon as you complete at least one set at the planned weight with the target reps, so progression can move forward earlier. • Fine weight control – Use 0.5 kg increments when creating programs and editing 100% working weights for smoother, more precise loading. • Weekly set tracking – See how many sets each muscle group gets per week and balance your volume with a simple training map. • Cardio training builder – Create your own interval-based cardio sessions or use existing cardio workouts on a dedicated cardio screen. • Adaptive overload – Increase reps within your chosen range and let the app raise the weight automatically once you reach the top. • Plateau detection and deloads – If you fail to complete an exercise for several sessions, TrainingOP suggests around a 10% weight reduction so you can rebuild and push past sticking points. • Light days and recovery – Easily add 50% intensity days to keep frequency high while reducing stress on joints and the nervous system. • Custom programs and sharing – Use prebuilt plans or design your own, then export and import programs via JSON to share or back them up. • Intelligent rest timer – Rest times adapt to intensity and include a subtle pulse in the last seconds, smoother text scaling and a high-contrast rest colour for better visibility. • Clear summaries and stats – SummaryCard highlights your max reps and shows a set-by-set breakdown, while statistics reveal weekly volume trends and muscle-group workload. • Polished cross-platform UI – Smoother BottomTab animations and layout tweaks improve readability and responsiveness on both iOS and Android. TrainingOP is for lifters who want long-term strength and muscle gains without burning out. The app’s self-adjusting programming keeps your training productive whether you progress quickly or slowly.
