Warm-Up Calculator

Build ramp sets from your work weight. The target is readiness, not fatigue: each warm-up should make the first work set more predictable.

Keep warm-ups crisp. They should prepare you, not fatigue you.

Example warm-up for 225 lb

This example uses a moderate barbell work weight. Heavier singles usually need more jumps; lighter volume work can use fewer.

Lift-specific warm-up advice

Scroll table horizontally

Lift Advice
Bench press Use smaller jumps near the top if shoulder or elbow position feels different from the empty bar.
Squat Add one extra single when the work weight is heavy enough that depth and bracing need a check.
Deadlift Start from plates at normal bar height if empty-bar pulls do not match the lift.
Overhead press Keep warm-up reps low because small shoulder fatigue can change the work set quickly.

Warm-ups and confidence intervals

If a 1RM calculator gives a wide range, treat that as uncertainty. Use the lower end for today, take smaller warm-up jumps, and let the final warm-up single decide whether the planned work weight is still reasonable.

If the final warm-up moves like RPE 9, the work weight is too aggressive. If it moves fast and matches the intended technique, the work set is more likely to fit the plan.

FAQ

Should warm-up sets feel hard?

No. Warm-up sets should prepare joints, positions, and bar speed without creating fatigue before the first work set.

How many warm-up sets do I need?

Use fewer jumps for light work weights and more jumps for heavy low-rep work. The final warm-up should confirm readiness, not test strength.

Should I warm up differently when my 1RM estimate has a wide range?

Yes. If your estimated 1RM range is wide, use the conservative end for work sets and add smaller warm-up jumps near the top.
