{"assets":{"app_about":{"about_data":{"description":"Muscle Builder is a workout app built for men who want to build muscle, increase strength, and train with structure. Follow a 28-day progressive program designed with a 7-days-per-week cycle × 4-week progression, covering every key muscle group—from adaptation to strength improvement—so you can see real results.

Whether you train at home, in the gym, or anywhere, Muscle Builder helps you stay consistent and push forward—week after week.

Why Muscle Builder
28-Day Progressive Workout Plan
A complete 4-week muscle building program with increasing intensity. Train smarter with a clear schedule and a progressive structure.

Full-Body Muscle Group Coverage
Workouts target the areas that matter for men’s physique and performance:
Chest • Back • Shoulders • Arms • Core • Legs

Strength Training That Fits Your Setup
No need to choose a “home only” or “gym only” plan. Train with what you have:
- Bodyweight training
- Dumbbell workouts (recommended if available)
- Flexible options based on your equipment and preference

Daily Training Rhythm (7 Days/Week)
A consistent weekly loop helps you build habits, maintain momentum, and avoid “what should I do today?” planning fatigue.

From Beginner Adaptation to Strength Gains
The program starts manageable, then builds intensity progressively—ideal for beginners who want a structured start and intermediates who want a focused plan.

Perfect for You If You Want To:
- Follow a men’s workout plan made for muscle growth
- Build a stronger chest, back, shoulders, arms, core, and legs
- Train with dumbbells or bodyweight, at home or at the gym
- Commit to a clear 28-day program and stay consistent

Start today and take your training seriously—Muscle Builder is your 28-day roadmap to more muscle and more strength.","icon_cdn_path":{"32x32":"https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/6260b470-47ba-11f1-bf37-b7821fcbaeb0/32x32","64x64":"https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/6260b470-47ba-11f1-bf37-b7821fcbaeb0/64x64","128x128":"https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/6260b470-47ba-11f1-bf37-b7821fcbaeb0/128x128"},"primary_category_id":39,"publisher_url":"https://play.google.com/store/apps/developer?id=BLUEBASE","screenshot_urls":["https://play-lh.googleusercontent.com/uf52fp8pUVr93e6i17NjPQQWS5s0z4CYKKSzy2mfMccQW1Xpxz34sZUw6NefE8W7tji_X7d_x9Mml8idNUua","https://play-lh.googleusercontent.com/qgUIRdqZzqRZYWRovBTUDgKXNSM5ZX42-HL5fGnv2iSvHclxoIynj8hKXTF-GnJMW962OleMIA1Ja3GhL_A7aw","https://play-lh.googleusercontent.com/SVFBuN526w_38cY1yaquOSl3nkjM-LHkiEpsxpdgrhE77Oj8NtXrKAtIeSnBRqkJm2VjdcCeecaw_EjJPWKYUmI","https://play-lh.googleusercontent.com/R6HOZmDlyVCm88o5eXzQ5xGwDFn8dfwfrw0TsgaiKRK22pHtNuUnHv-8hANgwX8MXXeBEQl0H-D7wTvRRqUH","https://play-lh.googleusercontent.com/zdwOZ946eLAnbyBf2LCK1t0rLEGoCqWYWmkQpmCvtwIWXjYLqiOsFHv8_a1bXFgMNX23yuigEjg1pZQYubFCJQ","https://play-lh.googleusercontent.com/7vJ9ncHQIE2Roubm76bFmFTJldY9ViaMI5oDhwqm-1kUS4Sj3N6Air0he_2uNcKJ-2E-5w4nnJ12xvQEoLVWqGU","https://play-lh.googleusercontent.com/JKS1MKlnvQi0Mw9B9oZAdBV8-e1n0WbDkiMTZWn_g7KpEFZ_jH5FCeUit9E6XuMI4RBMNHSyftEnYyQs8niwxJg"],"name":"Muscle Builder","app_id":"muscles.gym.buildmuscles.athome","category_ids":[39,16],"released_on":"2026-04-28","publisher_id":3306191,"url":"https://play.google.com/store/apps/details?id=muscles.gym.buildmuscles.athome","publisher_name":"BLUEBASE","icon_url":"https://play-lh.googleusercontent.com/lgR8AUG5OZxfE9hA1qOL0vZYLuYTXVNMO_keFI23OZocYQxxue-Sp-vL1QrPkyhDX1EShqUk60CyUECo0oMD","price":0.0,"screenshot_cdn_paths":["https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/63bb6270-47ba-11f1-bf37-b7821fcbaeb0/640","https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/656c94e0-47ba-11f1-bf37-b7821fcbaeb0/640","https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/66838320-47ba-11f1-bf37-b7821fcbaeb0/640","https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/67cd8f50-47ba-11f1-bf37-b7821fcbaeb0/640","https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/69dc9930-47ba-11f1-bf37-b7821fcbaeb0/640","https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/6b073680-47ba-11f1-bf37-b7821fcbaeb0/640","https://d1nxzqpcg2bym0.cloudfront.net/google_play/muscles.gym.buildmuscles.athome/6cc7f950-47ba-11f1-bf37-b7821fcbaeb0/640"],"avg_release_interval":"12 days","categories_list":[{"category_id":39,"category_name":"Applications","type":"primary","is_performance_available":false},{"category_id":16,"category_name":"Health & Fitness","type":"secondary","is_performance_available":true}],"iap_present":false,"ads_present":true,"subtitle":"Build muscle fast with smart workout plans, progress tracking, and gym routines.","released_date_formatted":"Apr 28, 2026","released_on_dev_date_formatted":null},"ratings":{"total_ratings":6,"avg_rating":4.5,"ratings_breakdown":{"3":0,"4":3,"5":3,"1":0,"2":0}},"versions":[{"version":"1.0.3-beta","release_date":"2026-04-28","description":null,"app_id":"muscles.gym.buildmuscles.athome","formatted_release_date":"Apr 28, 2026"}],"filters":{"store":"google_play"},"other_data":{"store_id":"muscles.gym.buildmuscles.athome","file_size":0,"os_compatibility":"Android ","age_rating":"Everyone","languages_list":[],"permissions":[{"category":"Other","permissions":[{"name":"ACCESS_NETWORK_STATE","description":"Allows applications to access information about networks.","category":"Other"},{"name":"ACCESS_WIFI_STATE","description":"Allows applications to access information about Wi-Fi networks.","category":"Other"},{"name":"FOREGROUND_SERVICE","description":"Allows a regular application to use Service.startForeground.","category":"Other"},{"name":"INTERNET","description":"Allows applications to open network sockets.","category":"Other"},{"name":"POST_NOTIFICATIONS","description":"Allows an app to post notifications.
