Switching workout apps is easy when you have logged three sessions. It is much harder when your training history includes years of workouts, saved routines, body measurements, exercise notes, and technique sets.
That history matters. A hypertrophy app cannot give useful progression guidance if it treats your old training as disposable.
What a Good Hevy Import Should Preserve
At minimum, a serious import flow should keep the data you actually use when deciding what to train next:
- Completed workouts
- Original workout names
- Exercise performance history
- Saved routines or recurring templates
- Body weight and supported measurements
- Exercise notes
- Warmup, drop, failure, and rest-pause set context where possible
This is not just an archive problem. If your past sessions are preserved well, the new app can help you understand recent load, reps, effort, weekly volume, and exercise selection without making you start from zero.
Why Mapping Exercises Matters
Workout apps often name exercises differently. One app might store "DB Incline Bench Press" while another uses "Dumbbell Incline Press."
A good migration flow should ask you to review those matches before import. Silent mismatches are expensive because they split your performance history across duplicate exercises. That makes progression look worse than it really is and can hide useful PRs or volume trends.
Routines Are Training Data Too
Many lifters think of routines as setup, not history. In practice, saved routines are part of the training record.
If you trained from an upper/lower split, push/pull/legs split, or custom physique plan, importing only completed workouts leaves out how you intended to train. A better import preserves reusable templates so you can train from them immediately after moving apps.
Measurements Belong With Progress
Hypertrophy is not only about load on the bar. Body weight, tape measurements, and progress photos help explain what strength and volume changes mean.
For example, a bench press plateau during a cut is different from the same plateau during a body-weight gain phase. Keeping measurement history near progress review makes that context easier to read.
The Jacked Approach
Jacked is built as an iPhone hypertrophy tracker around live session execution and progress review. Its import work is designed to preserve Hevy training context that lifters care about:
- Hevy routine patterns can become usable training days in an active plan.
- Workout names and session notes remain recognizable in history.
- Exercise mapping is reviewed before import continues.
- Body weight and supported tape/body-fat measurements can be imported.
- Exercise notes and set technique labels remain visible where the app has matching history surfaces.
The point is simple: your old logbook should become useful training context, not a dead backup.
After Import, What Should You Check?
Once your data is in a new app, review a few high-value areas before your first session:
- Check that your main lifts are mapped to the right exercises.
- Confirm saved routines have the right training days and exercise order.
- Open recent sessions and verify set types, notes, and workout names still make sense.
- Review body weight and measurement history if you imported body-composition data.
- Start with conservative progression targets until you trust the new app's history view.
Bottom Line
The best workout tracker migration is the one you do not notice during training. Your next session should already know what you did before, what you planned to do, and what a reasonable next target looks like.
That is the standard a hypertrophy app should meet when it asks you to leave an old logbook behind.
