🏋️ Warm-Up & % Calculator

Enter a known 1RM or a recent set (weight × reps) for up to three lifts. Get a smart warm-up ramp, a full %-of-1RM table with rep guides, and a target-reps → weight lookup. Round to your bar setup.

How to use it

Pick a lift, enter your known 1-rep max or a recent working set (weight × reps — we estimate your 1RM with the Epley formula). The tool builds a warm-up ramp from ~40% up to ~90% of your max with descending reps, then gives you the full 50–100% table with rep guides and a lookup that converts any rep target into a working weight.

Why warm up with percentages?

Ramping in structured percentage jumps primes the nervous system, grooves technique, and reduces injury risk without draining the working sets. It's the same approach used in most evidence-based strength programs — now automated so you don't have to do the math between sets.

Estimates are starting points, not prescriptions. A directly tested 1RM is always more accurate than a formula. — Coach Scharnick, CSCS · B.S. Exercise Science
