About
ONSET is the gym app that actually makes you stronger.
No more guessing. Onset tracks your volume per muscle, adjusts your weights automatically, and tells you when to push or recover. Whether you're a beginner or advanced, it adapts to you.
VOLUME PER MUSCLE
• Weekly sets per muscle with color-coded zones: not enough, minimum, optimal, too much
• See instantly if you're doing enough — or overdoing it
• 12-week history with trends and advice
PROGRESSIVE OVERLOAD
• Weights adjust every session based on your performance
• Real-time personal record detection
• Progress curves for every exercise
RECOVERY
• Body map showing fatigue for each muscle
• Overtraining alerts + light week suggestions
• Post-session feedback: pump, soreness, performance
PROGRAMS
• Generate your program based on your goals and equipment
• PPL, Upper/Lower, Full Body and more
• Adapts to your level and experience
IN SESSION
• Rest timer with voice announcements
• Rate each set by effort: easy, moderate, hard, all out
• Swap exercises mid-workout if needed
277 EXERCISES
• Animated GIFs for every movement
• Gym, home, bodyweight
