## What is Muscle Gym Diary?

**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. No more rebuilding the same workout every week.

**DETAILED ANALYTICS**
- Volume tracking with daily progress ring
- Weekly intensity trend charts
- Monthly calendar view with activity heatmap
- Estimated 1RM calculations (Epley formula)
- Exercise-specific history and past performance lookup

**REST TIMER WITH LIVE ACTIVITY**
Start a rest timer and see it on your Lock Screen and Dynamic Island. Choose 60s, 90s, or 120s — stay focused between sets without unlocking your phone.

**CARDIO LOGGING**
Track running, biking, walking, swimming, and more. Log duration and type with automatic calorie and distance estimates.

**SHARE YOUR WORKOUTS**
Generate a clean, shareable workout card image to post on social media or send to your training partner.

**ADDITIONAL TOOLS**
- lbs/kg weight converter
- Interval timer for HIIT and circuit training
- Customizable exercise library organized by body part
- Support for lbs and kg with seamless conversion

Dark mode supported. No subscriptions. No ads. Just you and the iron.
