If you’ve been lifting seriously, you have data. Years of it, probably — in Hevy, in Strong, or both. That history is yours. It represents real work.
The problem is that starting a new app means starting from zero. Your coach has no idea you’ve been deadlifting 275 for a year. It doesn’t know your shoulder press has stalled at 95. You’re back to “add 5lbs and see how it goes” — the thing you outgrew three years ago.
That’s why Jacked can now import your history.
How it works
Export your workout history as CSV from Strong or Hevy (it takes about 30 seconds — Settings → Export), then open Jacked and go to History → Import. Pick your file, confirm your weight unit if you used Strong, and you’re done.
Jacked matches your exercise names against its library automatically. Strong’s naming resolves at essentially 100%. Hevy runs a bit lower — around 92% — and anything that doesn’t match gets added as a custom exercise so nothing is lost.
The import is idempotent, which means if you run it twice you won’t end up with duplicate sessions. And imported history doesn’t count against the retention window — it’s kept for the full two years.
Your coach uses it immediately
This is the part that matters. Your AI coach doesn’t need an onboarding period. Import two years of deadlifts and it can already see your progression curve, your stall points, where you were when you got injured, what worked. The next time you log a set, it’s working with your actual history — not a generic beginner model.
It also picks up your routines. If you’ve been running the same push/pull/legs split for a year, Jacked will detect those patterns and offer to create them as plans. You don’t have to rebuild your program from scratch either.
What it doesn’t do
A few honest caveats: this is iOS only for now, and it reads CSV exports only (not connected sync). Duration and RPE fields from Strong are parsed but not currently surfaced in the UI. And if your app uses kg, make sure you pick the right unit during the Strong import — there’s no unit column in their export format, so Jacked asks you to confirm.
If you’ve been waiting to switch because you didn’t want to lose your history, that’s not a reason anymore. Your data moves with you.
