Warm-Up Set Calculator

Warm-Up Set Calculator

This tool was built by Serge (MSc) using common warm-up practice. My background is a lifelong natural lifter with over a decade of drug-free training and a science background (MSc). My tools are for educational purposes and give practical guidance, not professional advice.

Jumping straight to a heavy working weight is a fast way to lift with poor form or pick up a strain. A few ramp-up sets prepare your muscles and groove the movement first. Enter your working weight and this tool lays out a simple set of warm-up loads leading up to it, so you arrive at your top set ready to go.

How This Works

The tool builds your warm-up as a percentage of your working weight, starting light and climbing in steps. Early sets use higher reps to raise your temperature and grease the movement, while later sets drop the reps as the weight rises so you stay fresh for the top set. Round each result to the nearest weight you can load.

Understanding Your Result

Each row is a set to do before your working weight, in order. Rest a little longer as the weight climbs. If a warm-up feels heavy on the day, add a set or take more rest. The goal is to feel ready, not tired, by the time you reach your working set.

Important Limitations

This is a general guide, not a fixed rule. Heavier lifts and big compound movements often need more warm-up sets than lighter or isolation work. Adjust to the exercise, the day, and how your body feels. Always include a general warm-up before your first lift.
