Warm-Up Set Calculator

Each warm-up set increases in weight while decreasing in reps. This gradually prepares your muscles, joints, and nervous system for the heavy working weight ahead without draining your energy reserves.

Higher reps at lighter weights prime blood flow and movement patterns. As the bar gets heavier, fewer reps keep you from accumulating fatigue. By the time you reach your working weight, your body is primed but not tired.

A common mistake is treating warm-up sets like working sets. The goal is activation, not exhaustion. Keep warm-up reps well below failure and rest 60–90 seconds between sets so you arrive at your working weight ready to perform.
