Cubex Fitness AI Workout Coach

No hype. No false promises. Just a serious training app that works if you do.

Cubex Fitness was built by a former professional athlete and amateur boxer who got tired of fitness apps that promise miracles and lock the real features behind a paywall. So this one is different: everything is included, everything is free, and the only thing that creates results is your own consistency.

Use it persistently and you'll see progress. That's the deal.

WHAT'S IN THE APP

• 250+ AI-built workout programs — designed for different ages, for men and women, from beginner to pro level, balanced by AI for real productivity.
• 300 exercises — a full library covering 14 muscle groups and 24 equipment types, with clear guidance and a one-tap YouTube video demo for every movement.
• Live heart rate while you train — connect Health Connect and see your pulse right on the workout screen. Works with Samsung Health and Galaxy Watch. Heart-rate history is saved into your journal.
• Your workout on your wrist — NEW Wear OS companion app: live set & rest timers, GO/REST control and heart rate right on the watch. Works with Galaxy Watch.
• Control it from your notifications — interactive workout controls in the notification shade and on the lock screen. Change sets without opening the app.
• Super-sets — group exercises back-to-back with no rest between them, exactly like on a real training floor.
• A real session engine — rep sets and timed sets, per-exercise rest timers, live calorie burn, and Easy or Advanced mode depending on how much control you want.
• Free Workout mode — start an empty session and build it as you go.
• Adaptive step goal — starts at 5,000 steps a day and grows with you as you keep hitting it.
• Train for any goal — burn fat, build muscle, increase stamina, improve flexibility, tone your body, stay fit, or recover from injury.
• 11 training styles — gym, home, outdoor, CrossFit, functional, cardio, boxing, HIIT, stretching, recovery, and yoga.
• Full workout journal & history — every set of every session, saved. It replaces your paper notebook.
• Progress charts & goals — weight, calories, per-exercise records, and body measurements, with goals attached to each.
• Built-in Timer & Tabata — for fast, focused HIIT sessions.
• Make it yours — build your own programs, workouts, and exercises, and design custom charts and goals.

WHY CUBEX FITNESS IS DIFFERENT

Built by an athlete, not a marketing team. The training programs come from someone who actually trained and competed.

Genuinely free. No hidden fees. No "premium" features locked away. No subscription. No ads. The whole app is yours.

Works offline, no account required — your data stays on your device. All your activity, history, heart rate, and measurements are stored locally — your progress belongs to you.

One app instead of a stack. Cubex Fitness replaces an AI coach, a heart-rate monitor app, and a paper notebook, so your daily training has everything it needs in a single pack.

You shape what's next. Live video workouts with an AI Coach are already on the way. Need something else? Ask the team and leave a review — good ideas land in the next updates.

Available in English, French, and Russian.

Whether you want a gym routine, a home workout, a Tabata timer, an offline workout journal, or a plan for injury recovery, Cubex Fitness keeps it all in one place.
