## What is Muscle State?

See your training, muscle by muscle.

Muscle State brings workouts, protein, sleep and body weight into one personal training log. Explore a visual muscle map, review the activity behind each region, and rewind the last 14 days to see how your estimated training load has changed.

A MUSCLE MAP YOU CAN EXPLORE
Log workouts with duration, effort and the muscles trained. Tap a muscle to see its recent workouts, time since mapped training and the explanation behind its color.

WORKOUTS, SLEEP, PROTEIN AND REST
Compare Workouts + recovery with Workouts only. Workouts add load to the muscles you select, while time between workouts reduces it. Completed-day sleep and protein totals relative to your saved goals can slow the following day's reduction. Missing records remain unknown rather than counting as zero.

YOUR DAILY TRAINING LOG
Record workouts, protein intake, sleep and body weight. Set personal protein and sleep goals, edit manual entries and explore your trends.

OPTIONAL APPLE HEALTH CONNECTION
Import recent workouts through Apple Health, including compatible workouts shown in Apple Fitness. Review editable muscle suggestions for supported activities and choose effort before adding imported workouts to your muscle map. You can also synchronize supported sleep, protein and body-weight records with your permission. Sync is started by you, and recent Health imports are limited to the last 14 days.

SLEEP SESSIONS, NOT FRAGMENTS
Imported asleep segments are grouped into sessions, with overlapping time counted once. Only imported sessions containing more than three hours asleep are shown. Short manual sleep entries remain available.

LOCAL AND PERSONAL
No account is required. Your logs are stored on your device. Muscle State has no advertising or third-party analytics and does not send your health information to the developer. Apple Health access is optional.

UNDERSTAND THE ESTIMATE
The muscle colors and percentages show experimental estimates of remaining training load, not measured biological recovery, readiness, injury risk or muscle growth. They depend on the workouts and other information you record and are not medical advice or a recommendation about whether it is safe to train.
