Dynamic Warm-Up Explained

In brief: A dynamic warm-up is a set of active, controlled movements done before running to prepare the body for the effort ahead. It typically includes movements such as leg swings, lunges, high knees and easy strides that gradually raise the heart rate, warm the muscles and rehearse the movement of running. A good dynamic warm-up helps running feel smoother from the start and is a simple, valuable habit.

What is a dynamic warm-up?

A dynamic warm-up is a short routine of active movements performed before a run, as opposed to standing still and holding stretches. It uses controlled, repeated movements such as leg swings, walking lunges, high knees, heel flicks and gentle strides to gradually wake the body up and prepare it for running. The movements flow rather than being held, which is what makes the warm-up dynamic.

How it works

The active movements gradually raise the heart rate and body temperature, increase blood flow to the working muscles and take the joints through ranges similar to those used in running. This prepares the muscles to contract more readily and rehearses the coordination of running, so that by the time the run begins the body is primed. The effect is a smoother, more comfortable start rather than easing into a cold, stiff effort.

Why runners use it

Starting a run cold, especially a faster or harder session, can feel sluggish and stiff for the first stretch. A dynamic warm-up reduces that by easing the body up to readiness first. It is particularly valued before interval sessions, races and faster running, where the body needs to be ready to work hard from early on, and it helps running feel better from the opening minutes.

How to use it

Spend a few minutes on a sequence of controlled movements before running, beginning gently and building gradually, often finishing with a few easy strides that lift towards running pace. Keep everything smooth and controlled rather than forcing big ranges or rushing. The harder or faster the session ahead, the more worthwhile a thorough warm-up becomes, while a very easy run may need only a few minutes of gentle movement.
