Muscu+: upper-body programs (Hypertrophy, Strength, Endurance, Explosiveness) with a haptic rest timer and alerts even in the background. Muscu+ is the ultimate upper-body training app designed for precision, motivation, and progress. Built for Apple Watch, it offers a complete and intuitive approach to muscle development with four structured programs: Volume, Strength, Endurance, and Explosiveness. Each workout day features detailed exercises, clear visuals, and concise tips for proper execution. Muscu+ helps you stay consistent with short yet efficient sessions, perfectly suited for both beginners and advanced users. This new version introduces full multilingual support — available in English, French, Spanish, and Vietnamese — so you can train in your preferred language. All exercises, advice, and menus are fully translated for a seamless user experience. Muscu+ focuses only on the upper body (chest, back, shoulders, arms) to provide targeted results without unnecessary complexity. No login, no tracking — just your progress, at your rhythm. Features: • 4 structured programs: Volume, Strength, Endurance, Explosiveness • Clear guidance for every exercise • Practical advice for recovery and form • Optimized display for Apple Watch Ultra and Series models • Multilingual interface (EN, FR, ES, VI)

  • This app hasn’t received enough ratings or reviews to display an overview.

Added a rest timer on Apple Watch: quick start 60/90/120s, pause/resume, add time (+10s) and stop. Haptics at 10 seconds remaining and at the end of the rest. Optional notifications so you’re alerted even when the app is in the background or the screen turns off. Improved usability to validate sets and start rests more easily.
