AX.GRIND is free training for people serious about their grind — real workouts, an AI coach, nutrition tools, and a community, with no subscriptions and no paywalls, ever. TRAIN • 300+ workouts from beginner to advanced, for gym or home • 1,200+ exercises, each with a form cue and a video tutorial • Sport-specific plans and structured multi-week programs • Every workout logged automatically — level up, build a streak, and track your all-time history LOCK IN A focus timer built for training days: set a duration, stay in the app the whole time, and earn XP for finishing. Leave even for a second and the session ends — no cheating yourself. GRIND BREATH A guided breathing exercise to reset between sets or before a session — pick 1 to 5 rounds. NUTRITION • A calorie and macro calculator built around your goal — cut, maintain, or bulk • A sample meal plan and a full breakdown of vitamins, minerals, and which foods to prioritize or limit • General education, not a diet plan — always check with a doctor or dietitian for anything personalized PROGRESS • Log your weight and watch a real trend line, not daily noise • Add a progress photo alongside each weigh-in and compare any two side by side • Track body measurements — chest, arms, waist, and more • Unlock achievements as you build real consistency AI COACH & BODY ANALYZER Ask the AI Coach anything about training, nutrition, or recovery. Upload a photo for the AI Body Analyzer to get a personalized plan recommendation. Both are AI-generated — not a replacement for a real doctor, trainer, or dietitian. COMMUNITY A forum and direct messages to share progress, ask questions, and stay accountable, plus a leaderboard ranked by XP. Report and block tools keep it safe, and every account can be deleted at any time. AX.GRIND is intended for users 13 and older. It provides general fitness and nutrition information for educational purposes only — it is not medical advice. Talk to a qualified healthcare provider before starting any new exercise or nutrition program.
