stimulus smart progression tells you exactly what to load next session — based on how your last sets actually felt. Plus an AI coach that knows your full training history. For lifters ready to train smarter.
Most lifters don't. They open their app, scroll back three sessions, and guess. The apps you use are notebooks with a timer. The programs that do think for you don't let you run your own. stimulus sits in the middle: your program, your decisions, but with real data backing every one.
Sets, reps, weight, RIR or RPE — your choice. Same speed as any app. Works offline.
stimulus reads your RIR trends across sessions and shows you exactly what to load. Not a fixed percentage — your actual readiness data.
Volume trends, e1RM curves, muscle balance. Your AI coach pulls from all of it — not just your last session.
Suggestions based on your actual proximity to failure — not arbitrary percentage jumps or fixed weekly increments.
AI coach that knows your full training history, current program, and recent trends. Not a generic chatbot.
34 templates or build your own. Not locked into a fixed system like RP Hypertrophy or Juggernaut AI.
Import from Strong, Hevy, Garmin FIT files, or screenshot import. Your training history comes with you.
Export everything as CSV or JSON at any time. Works offline. No lock-in, ever.
Completed workouts auto-sync as Weight Training activities. Garmin FIT import for pulling data in.
