What StrengthInsight does

Per-exercise progressionEstimated 1RM trend per lift (Epley formula) so you can see whether bench, squat and deadlift are actually improving.
Lift recordsPeak Load, Top Set Output, Best Session Total — automatically tracked across every session.
PR trackingDate of last PR plus a PR-drought counter per exercise. No more guessing how long you've been stuck.
Plateau detectionAuto-flag when a lift has been flat across recent sessions, with next-weight suggestions.
Recovery contextPair WHOOP recovery score with your lift performance — see when readiness is masking real progress.
AI next workoutRecovery-aware programming suggestions built from your last 5 sessions of training data.

How it works

  1. Screenshot or Sync a workout from WHOOP, Hevy, Fitbit/Google Health or Garmin, or connect WHOOP or Strava directly.
  2. Upload/Sync to StrengthInsight — AI extracts exercises, sets, reps and weights.
  3. Review your progression dashboard: estimated 1RM trends, lift records, plateau alerts, and an AI-generated next workout.

Why StrengthInsight exists

WHOOP Strength Trainer is a great session logger, and it now adds basic PRs and per-exercise trends. But it stops at the surface: no estimated 1RM line per lift, no plateau alerts when a movement stalls, and no link between your recovery and your output. StrengthInsight extracts your data from a screenshot and turns it into a deeper progression view — the layer WHOOP's basics don't reach.

WHOOP, Hevy, Fitbit/Google Health and Garmin users get the same screenshot analysis: per-exercise progression, plateau detection and recovery-aware next-workout suggestions, with no manual logging.
