How to read the result
Enter your last leg press set and get your next target. The notes below show the assumptions behind that recommendation.
Leg Press Next Set Calculator
Enter your last leg press set and get your next target. Leg press progression works best when foot placement, depth, and sled setup stay consistent. Jacked turns the set into a clear next move.
Log the set in Jacked and the next target stays with the workout.
How Jacked chooses your next leg press set
The calculator reads load, reps, and RIR, then applies leg press-specific progression context. Leg press progression works best when foot placement, depth, and sled setup stay consistent.
When to add weight
Add load when you hit the top of the target range at the planned RIR without changing the leg press standard.
When to add reps instead
If the load jump is large or reps are still inside range, keep the same leg press weight and add reps first.
Common mistake
Do not add plates by shortening range of motion.
Short answers
What should I lift next for leg press?
Use the smallest load jump when reps, RIR, and execution all support it. Otherwise add reps or hold load.
Why does RIR matter for leg press?
RIR separates a repeatable progression signal from a set that only succeeded because effort spiked.
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
Uses reps plus RIR to estimate effective reps to failure, then applies rep-range progression rules: add load, add reps, hold, or reduce.
Assumptions
Best signal comes from recent sets in a stable rep range with consistent technique and a clear RIR estimate.
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.
