How to read the result
Estimate your romanian deadlift max and get a useful target. The notes below show the assumptions behind that recommendation.
Romanian Deadlift 1RM Calculator
Estimate your romanian deadlift max and get a useful target. A romanian deadlift e1RM is useful when the set standard is consistent. Do not add weight by turning the lift into a shorter-range conventional deadlift.
Log the set in Jacked and the next target stays with the workout.
What romanian deadlift e1RM means
This is a ballpark estimate from a submaximal romanian deadlift set, not a guaranteed max attempt.
Why RIR improves the estimate
The same reps at different effort levels imply different strength. RIR makes the estimate more useful.
Best data for this lift
Use recent sets where romanian deadlift execution matched your normal standard.
Common mistake
Do not add weight by turning the lift into a shorter-range conventional deadlift.
Short answers
Is this romanian deadlift 1RM exact?
No. It is a training estimate. Use it for trends and targets, not as proof of a tested max.
Should I test a true 1RM?
Only when it fits your goal, skill, and recovery. Most hypertrophy training does not require frequent max testing.
Jacked turns your training history into next-set targets, RIR tracking, rest timing, smart warm-ups, PRs, and progress feedback.
Method, assumptions, and privacy
Method
Combines common e1RM formulas where valid, then adds rep maxes, percentages, and a useful target instead of stopping at a max estimate.
Assumptions
High-rep and sloppy sets are lower-confidence. Treat e1RM as a trend and targeting tool, not a guaranteed max.
Privacy
Inputs are handled in the browser for the web tool experience. Jacked should only store lifting data when a user chooses to log it in the app.
Check the method before you trust the number. Bad inputs still produce tidy-looking outputs.
This is one set.
Jacked does it for your whole workout: next-set targets, RIR, rest timing, warm-ups, PRs, and progress feedback.
