The honest answer most lifters need to hear up front: WHOOP doesn't accept third-party workout imports for Strength Trainer in 2026. There's no CSV import, no API push, no "Connect to Hevy" button. Here's what the actual options look like, when each one is worth the effort, and the screenshot-based workflow that gives you a unified progression view without re-logging anything.

WHOOP doesn't accept workout imports. You can either (a) manually re-log each session in WHOOP Strength Trainer to feed Strain, or (b) skip the re-log entirely and use StrengthInsight to read a screenshot from your source app (Hevy, Strong, FitNotes, etc.) and combine the data with your WHOOP recovery view automatically. Option (b) takes 10 seconds per session.
WHOOP's API exposes recovery, HRV, sleep, and strain data outbound — but the Strength Trainer data layer is closed both ways. WHOOP doesn't expose your set-by-set data to third parties, and equally it doesn't accept third-party workout data inbound. The result is the same in practice: your strength data has to be entered inside WHOOP to live inside WHOOP.
WHOOP's May 2026 announcement listed "third-party app integrations" as a future roadmap item, but with no ship date and no specific mention of workout imports. So the practical answer in 2026: don't wait.
| Option | Effort per workout | Strain integration | Progression view |
|---|---|---|---|
| Manually re-log full session in WHOOP | 5–10 min | ✓ Full | ✗ Still no per-exercise trend |
| Quick "summary" log in WHOOP (top exercises only) | ~1 min | ✓ Approximate | ✗ Still no per-exercise trend |
| Skip WHOOP log + use StrengthInsight | 10 sec (screenshot) | ✗ No | ✓ Full per-exercise trends + PRs |
The honest tradeoff: if Strain integration is non-negotiable for you, options 1 or 2 are unavoidable. If your priority is per-exercise progression visibility (which WHOOP itself doesn't yet show, even with a full re-log), option 3 gets you that for free without any re-logging at all.
If you decide to mirror your Hevy / Strong / FitNotes session inside WHOOP, the workflow:
This is the only path that gives WHOOP a complete set-by-set picture of the session. The cost is 5–10 minutes per workout of mostly manual data entry that you've effectively done twice (once in your real logger, once in WHOOP). For most people, this gets abandoned within two weeks.
If you want your strength session to count toward daily Strain but don't care about WHOOP having full set-by-set detail, log a quick summary:
This takes about a minute and feeds WHOOP enough information for Strain to register that you trained. It's the pragmatic middle ground — you lose set-by-set fidelity inside WHOOP, but you gain a representative Strain value.
The shortcut
The fastest path: screenshot the workout in your source app (Hevy, Strong, FitNotes, your spreadsheet, your gym whiteboard). Upload it to StrengthInsight. AI extracts every exercise, set, rep and weight. You get estimated 1RM trends, PR tracking and plateau alerts in one progression view — alongside your WHOOP recovery data. Free, 10 seconds per session, no manual entry inside WHOOP at all.
Try StrengthInsight free →This isn't an import into WHOOP per se — it's a unified progression view that doesn't need WHOOP to be the system of record for strength data. For most lifters that's a better answer than re-logging anyway, because even a fully re-logged WHOOP Strength Trainer session doesn't show per-exercise progression. You'd be doing the data entry work without getting the progression view at the end of it.
The same logic applies. There is no direct import from Strong, FitNotes, Caliber, or a spreadsheet into WHOOP Strength Trainer. The options are identical:
StrengthInsight reads screenshots from any of these apps — it's source-agnostic for the most part. The constraint is just that the screenshot needs to show exercise names, sets, reps and weights clearly.
No. WHOOP doesn't accept third-party workout imports for Strength Trainer in 2026. Options are manual re-log or skip-and-unify via StrengthInsight.
Not for Strength Trainer. WHOOP doesn't currently support CSV imports of strength workouts.
No automated path exists. Re-log manually inside WHOOP, or use StrengthInsight to read screenshots from Strong/FitNotes for the progression view without needing data inside WHOOP.
Third-party integrations are on WHOOP's roadmap, but no ship date or commitment to workout imports specifically. Don't wait.
Only if Strain matters to you. A quick top-set summary log takes about a minute and gives WHOOP enough to credit Strain — full set-by-set re-logging is rarely worth the time.
The unified workflow
Use whatever app you prefer for logging, screenshot the session, let StrengthInsight extract the data and pair it with your WHOOP recovery view.
