Hevy to Strong
Moving from Hevy to Strong is not a normal CSV import.
A lot of app switching is reversible. Hevy to Strong is trickier because Strong is export-friendly but not import-friendly in the same way.
Before you spend hours reshaping a Hevy CSV, confirm the destination app actually has an import feature for historical workouts.
Step-by-step checklist
- 1
Export Hevy workouts and measurements before leaving.
- 2
Check Strong's current help center for import support before editing any CSV.
- 3
If Strong still has no historical import path, decide whether manual backfill is worth it.
- 4
Manually recreate only the routines you will use going forward.
- 5
Keep Hevy export files archived for old PRs, notes, and reference.
- 6
If full history matters, pick a destination that supports Hevy CSV or flexible CSV import.
The blocker is destination support
CSV conversion only helps when the destination app has an importer. Strong's own export documentation says exported files cannot be imported back into Strong.
That is the key difference from Strong to Hevy. Strong can give you a spreadsheet-friendly history file, but that does not mean it can consume another app's file.
| Path | Practical status | Best move |
|---|---|---|
| Hevy workouts to spreadsheet | Good | Export and analyze in Sheets or Excel. |
| Hevy workouts to Strong | Weak | Expect manual entry unless Strong adds import support. |
| Hevy routines to Strong | Manual | Recreate current templates only. |
| Hevy history to flexible importer | Better | Use an app that explicitly supports Hevy or generic CSV. |
What to migrate manually
If you still want to use Strong, do not try to backfill every set first. Recreate the templates you will run this month, then keep the Hevy CSV as an archive for old PRs and notes.
Historical perfection is expensive. Current training continuity matters more.
When not to switch
If your main reason for switching is old history, do not move into an app that cannot import that history. Pick the destination around data portability before you pick it around interface taste.
That is especially true if you have hundreds of completed workouts or years of custom exercise names.

FAQ
Fast answers
Can Strong import Hevy data?
Strong's help center says exported CSV files cannot be imported back into Strong. Unless Strong adds broader import support, Hevy-to-Strong history migration is mostly manual.
Is it still worth exporting Hevy?
Yes. Keep the export as an archive and use it for spreadsheets, PR lookup, or migration to an app that supports Hevy/generic CSV import.
What should I recreate manually?
Recreate the routines you will actually use next, plus any key custom exercises. Do not spend days manually entering old workouts unless you truly need that history inside Strong.
