Warm-up Duration by Workout Calculator
Estimate how many minutes to warm up before a session based on the workout type, its intensity and the temperature.
How it works
Warm-up = base(type) + intensity adjust + temperature adjust, clamped 4–25 min · explosive & cold add time
A warm-up raises muscle temperature, primes the nervous system and rehearses the movements you are about to do, which improves performance and lowers injury risk. Explosive and high-intensity sessions need more preparation than easy cardio, and cold environments need more still because tissues start colder. Split the time into a general pulse-raiser followed by specific, gradually harder movements that mimic the workout.
Worked example
Strength training has an 8-minute base. At moderate intensity (+0) in a cold gym (+3), that is 11 minutes — roughly 4 minutes of general pulse-raising and 7 minutes of ramp-up sets before your working weights.
Frequently asked questions
What makes a good warm-up?
Two phases: a general pulse-raiser (easy cardio or dynamic movement) to raise temperature, then specific preparation that rehearses the session — lighter sets before heavy lifts, or strides before a fast run.
Should I stretch during a warm-up?
Favor dynamic movements over long static stretches. Prolonged static stretching just before power or strength work can temporarily reduce force output; save longer holds for after training.
Do I need more warm-up when it is cold?
Yes. Cold muscles are stiffer and slower to reach working temperature, so extending the warm-up in cold conditions helps protect against strains.
