**Muscle Gym Diary** is a powerful, beautifully designed strength training tracker built for lifters who want to get stronger, stay consistent, and see real progress. **LOG WORKOUTS YOUR WAY** Record every set with weight, reps, and RPE. Swipe to delete, reorder exercises, mark warm-up sets, and track assisted exercises. One tap to add sets — no friction, no clutter. **PERSONAL RECORDS, AUTOMATICALLY TRACKED** Hit a new PR? You'll know instantly. Muscle Diary detects when you lift heavier than ever before and highlights it with a trophy — so every milestone gets the recognition it deserves. **AI-POWERED WORKOUT GENERATION** Let Apple Intelligence create custom workouts tailored to your level and focus area. Choose your difficulty, target muscle groups, and let the AI trainer handle the rest — complete with sets, reps, and weight suggestions based on your history. Apple Intelligence features require iOS 26 or later and are available on iPhone 16 and later, iPhone 15 Pro, and iPhone 15 Pro Max. Apple Intelligence is not available in all languages or regions. AI features run on-device — your workout data stays private and is never sent to external servers. **MUSCLE HEATMAP** See which muscles you've trained recently and which need attention. A visual body diagram with front and back views color-codes your training recency — from red-hot (trained today) to cool blue (time to train again). **WORKOUT TEMPLATES** Save your favorite routines as templates and load them in seconds.
