PrimeXMR is an offline-first workout tracker, gym log, and interactive muscle encyclopedia built for people who want to train with purpose. Plan strength workouts, record sets and reps, explore muscle anatomy, and review your training history in one Android app.

Starting a routine or refining your lifting program? PrimeXMR helps you spend less time organizing and more time training.

**Build workouts around your goals**

Use the Smart Workout Builder to create sessions based on what you want to accomplish. Choose strength, muscle gain, fat loss, or recovery as your focus. Adjust workout duration, filter by available equipment, and generate a plan that fits your session.

• Generate a workout for your selected training goal.
• Adjust the session length to fit your schedule.
• Filter movements by equipment you have access to.
• Regenerate a workout when you want a different plan.
• Lock exercises you want to keep while changing the rest.

Shape your training around the time, equipment, and goals you have today.

**Log sets, reps, and weights**

Turn your workout plan into a record of what you actually did. Start from a built-in routine or launch a custom workout through Quick Start. Enter weight and reps, track your sets, and mark exercises complete as you move through the session.

• Record your resistance training sessions.
• Track weights, repetitions, and completed sets.
• Use ready-made workout templates or start from scratch.
• Keep a personal gym log without relying on memory.
• Review workout summaries after training.

From upper-body sessions to full-body workouts, see what you have done over time.

**Follow your strength progress**

Look back at completed workouts, compare sessions, and identify personal milestones.

• Browse previous workouts in the calendar view.
• Review your training history and session summaries.
• Track personal records (PRs) as you improve.
• See workout volume calculations for logged training.

Use your records to make more informed choices about your next session, whether you are adding weight, adjusting reps, or repeating a successful routine.

**Explore an interactive muscle encyclopedia**

PrimeXMR is more than a workout log. Its muscle encyclopedia combines a front-and-back body map with anatomical diagrams so you can explore the muscles involved in movement.

• Switch between front and back muscle views.
• Select muscle regions to learn more about them.
• Explore muscle details and fiber-type information.
• Find suggested movements associated with selected muscles.
• Use the recovery map as a visual starting point for planning a session.

Explore your chest, back, shoulders, arms, legs, and other regions to make exercise choices more intentional.

**Find and organize exercises**

Search the exercise library by name, or narrow your options using filters for muscle group, equipment type, and workout intent. When you need something more specific, create and save your own custom exercise.

Use the exercise finder to plan gym sessions, organize strength training, or replace a movement when equipment is unavailable.

**Workout tracking that works offline**

Your training should not stop when the signal drops. PrimeXMR is designed for offline-first use, including workout tools and muscle encyclopedia content. Open the app at the gym, at home, or while traveling without depending on a constant internet connection. Choose a light or dark display to suit your preference.

**A practical fitness companion**

PrimeXMR brings together a workout planner, weightlifting log, progress tracker, exercise library, and muscle anatomy guide. It is built for people who want useful training tools without making their gym routine complicated.

Build a session. Log the work. Learn the muscles. Review your progress. Make the next workout count.

Optional in-app Pro upgrades are available for additional functionality.
