Ninja Lifts is the gym brain in your pocket. Built for lifters who are serious about progress โ€” not fluff. TRACK YOUR WORKOUTS Log every set, rep, and weight in seconds. Auto rest timer starts the moment you finish a set. Swap exercises, track RPE, and let the app suggest your next weight based on how hard your last session felt. NEVER MISS A PR Every personal record is automatically detected and saved. Bench, squat, deadlift โ€” your Big 3 are tracked with full history. See exactly when you peaked and where to push next. AI WEEKLY PLAN Generate a full 7-day training split in seconds. Push Pull Legs, Upper Lower, Bro Split, Full Body โ€” customised to your goals. If you miss days, the AI detects it and rebuilds your plan automatically. NUTRITION & MACRO TRACKING Search 85+ foods with real nutrition data. Scan any barcode to instantly pull calories, protein, carbs and fat. Set your daily targets and watch your macros fill up in real time. AI PHYSIQUE ANALYSIS Add before and after photos. The AI analyses your body composition, detects muscle imbalances, estimates body fat, and gives you a personalised training focus โ€” all from your photos. MUSCLE ACTIVATION MAP See exactly which muscles youโ€™ve trained this month. The body map lights up based on your actual workout history โ€” so you can spot imbalances before they become injuries. READINESS CHECK Before every session, rate your sleep, energy, and soreness. The app calculates your readiness score and tells you whether to go heavy, train smart, or take a rest day. PROGRESS CHARTS Glowing weekly volume chart, full workout history, muscle recovery tracker, and smart coaching insights โ€” all in one place. NO SUBSCRIPTION. NO ADS. JUST LIFTING.
