The Plan Generator creates a hypertrophy-optimized training week in 60 seconds. Free forever, with every training feature. Plus: every Pro feature free for 60 days. BUILT FOR HYPERTROPHY Every feature is engineered around what actually drives muscle growth: progressive overload, weekly volume in the productive range (MEV → MAV → MRV), proximity to failure, and consistency over time. Track sets per muscle group, hit weekly volume targets, see exactly which muscles are progressing. FAST. REALLY FAST. Weight. Reps. Done. Rest timer starts automatically. Previous weights are always visible. You focus on lifting — the app handles the rest. TRACK EVERY SET LIKE A PRO Supersets with guided alternation. Warm-up, drop, and failure set tagging. Optional per-set RIR (Reps in Reserve) — so your trends reflect true effort, not just numbers. Edit completed workouts anytime. Smart rest alerts on phone and watch. SWITCHING FROM HEVY, STRONG OR ALPHA PROGRESSION? Import your complete training history with one tap. Keep all your PRs, exercises, and session data — nothing gets lost. YOUR STRENGTH & MUSCLE, VISUALIZED Personal records are detected and celebrated automatically — weight PRs, rep PRs, and estimated one-rep max. Tap any PR to see your progress with interactive charts and trend analysis. The Progress Check tells you if each muscle group is progressing — productive, stagnating, or needs more volume. After an injury or break? Reset your PRs and start fresh.
