Workout Tracker – Onyx Coach

Build muscle and track every gym workout with full control. Onyx Coach is a powerful workout tracker and gym log built for lifters who take their training seriously. If your goal is strength, size, or just getting stronger each week, this gym workout app keeps you focused and consistent. Start training with purpose!

This isn’t another generic workout app. Onyx Coach is a gym tracker, a weight lifting workout planner, and a muscle booster all in one. Instead of random exercises, you’ll build a real gym routine tailored to your goals. You don’t need to be a personal trainer to create your plan — this app gives you the structure to make it your own.

Beginners building their first gym workout and experienced lifters chasing long-term strength goals will both stay focused with Onyx Coach. Use it as your gym workout planner, workout journal, or a strong workout tracker that keeps every lift in check.

Track Every Set, Every Rep

Log each set in the workout log with full detail and keep your sessions organized with the gym set tracker. Solid tracking is key for building muscle and increasing strength over time. A clear gym workout routine brings structure to your training and drives steady progress.

Monitor Muscle Progress with a Clear View

Onyx Coach includes a gym progress tracker that helps you visualize your results. See how your lifts improve over time and keep an eye on where you’re growing. This is also a great progressive overload tracker — plan your increases, build your strength, and hit new goals.

Build Your Own Workout Plan

You're in full control of your workout planner. Add exercises, group them into a gym routine, and save templates that match your training style. You can build upper/lower splits, push-pull-legs programs, or even classic bodybuilding rotations—the workout builder fits the way you train

Keep a Fitness Journal That Works

Onyx Coach works as a clean, distraction-free fitness journal. Log your lifts, track your progress, and stay organized. Use the exercise log to track gym workouts, weight training, and more — all from a single view. If you've ever used spreadsheets or notepads to track training, this is your upgrade.

Built for real gym users, Onyx Coach avoids distractions. It’s a focused gym tracker with tools that actually matter: workout log, gym log, gym workout planner, and muscle tracking — without anything you don’t need. From casual weightlifting to serious strength training, it fits any level.

Smart Features for Focused Lifters

Use the weightlifting tracker to follow your routine, or create your own weight lifting workout planner. The app tracks what matters: reps, weights, exercises, gym sets. Add gym tips to your notes, build your own fitness plan, and follow a system designed to get results — without relying on videos or fluff.
