Stop guessing from soreness alone
Recent work by muscle group stays visible, so you know what a heavy session actually affected.
SuperFlex turns logged sets into muscle-level recovery context so the next session starts with better evidence than soreness alone.

Muscle Recovery Tracker
Each feature is built around a real training outcome, so you can make your next lifting decision with more confidence.
Recent work by muscle group stays visible, so you know what a heavy session actually affected.
When one muscle group is still recovering, you can shift attention to work that is ready.
Recovery context pairs with recent training volume so neglected muscle groups are easier to spot.
How It Works
SuperFlex keeps the main path fast while preserving the context serious lifters need.
Every exercise maps to primary and secondary muscle groups behind the scenes.
Muscles show as Fresh, Recovering, or Fatigued based on recent training history.
SuperFlex highlights fresh areas with lower recent volume so the next choice is easier.
Recovery tracking informs the decision, but sleep, stress, nutrition, and pain still matter.
Why It Matters
A generic rest-day timer treats the body as one unit. Strength training does not. SuperFlex adds muscle-specific context so you can push where it makes sense and hold back where fatigue is still high.
