Read the slope, not one workout
A single hard day can lie. The trend shows whether your training is actually producing strength.
Feature - 1RM TrackingPro
1RM tracking that shows
strength trends before PR day.
SuperFlex turns normal working sets into estimated 1RM trends so you can see whether strength is moving before you schedule a true max day.
1RM Tracking
What you can do with this feature
Each feature is built around a real training outcome, so you can make your next lifting decision with more confidence.
Use normal sets as data
Triples, fives, and controlled higher-rep work all contribute to the estimate without a dedicated test day.
Catch plateaus earlier
Flat curves make it easier to see when programming, fatigue, or recovery needs attention.
How It Works
Simple workflow. Real-world training flexibility.
SuperFlex keeps the main path fast while preserving the context serious lifters need.
1
Log working sets as usual
Enter weight and reps during training. There is no separate 1RM workflow to maintain.
2
SuperFlex estimates the session's top strength signal
The app uses an Epley-based estimate and favors useful working-set ranges over noisy outliers.
3
Review trends per exercise
Squat, bench, deadlift, rows, and variations each get their own strength history.
4
Adjust programming with better evidence
Use the curve to decide when to push, deload, repeat a block, or change the plan.
Why It Matters
Strength progress is usually visible before a PR happens.
Most lifters wait for a new top set to know training is working. Estimated 1RM tracking gives you an earlier signal from the work you are already doing, so the next programming decision is based on trajectory instead of hope.
- Avoid frequent true max tests.
- Compare different rep ranges on one trend.
- Use strength data alongside recovery context.

FAQ
Common questions about 1RM Tracking
What formula does SuperFlex use?
SuperFlex uses an Epley-based estimate: weight x (1 + reps / 30). The trend matters more than any single estimate.
Do I need to test a true one-rep max?
No. Estimated 1RM tracking is designed to use normal working sets so you can avoid frequent max-test sessions.
Does this work per exercise?
Yes. SuperFlex tracks estimated 1RM trends separately for each exercise you log.
How accurate is estimated 1RM?
Accuracy is strongest in lower rep ranges and varies by lifter. The most useful signal is the direction of the trend over time.
