Smart Warm-Up Calculator

Generate warm-up sets from your working weight. Warm up enough to perform, not so much that the warm-up becomes the workout.

Log the set in Jacked and the next target stays with the workout.

How to read the result

Generate warm-up sets from your working weight. The notes below show the assumptions behind that recommendation.

How the warm-up calculator works

Heavy compound lifts get more ramping sets. Isolation lifts get fewer. Recent exposure, soreness, caution, and preference can add or remove sets.

Heavy compound warm-ups

A common path is about 40% x 8, 60% x 5, 75% x 3, then 85-90% x 1 before working sets.

Isolation warm-ups

Most isolation lifts only need one or two warm-ups unless the load is unusually heavy or the joint needs extra preparation.

Common mistakes

Do not turn warm-ups into grinders. Keep them crisp, leave reps in reserve, and save effort for working sets.

Short answers

How many warm-up sets should I do?

Enough to make the working weight feel familiar without creating fatigue. Heavy compounds usually need more than isolation lifts.

Should warm-ups be close to failure?

No. Warm-ups should prepare the movement and joints while preserving effort for working sets.

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

Builds ramping sets from target load, movement type, recent heavy exposure, training status, and warm-up preference.

Assumptions

Warm-ups should prepare the working set without turning into hard training sets.

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.
