Should I static stretch before a workout instead?

Generally no, at least not as the main warm-up — moving stretches raise body temperature and rehearse the coming movement, while long held static stretches beforehand can temporarily reduce the muscle's power output. Save static stretching for the stretching generator or a cooldown instead.

How long should a warm-up take?

Long enough to raise a light sweat and rehearse the day's main movements at low intensity — often five to ten minutes, more before heavy or explosive training and less before a light session. Build gradually rather than watching the clock.

Warm-Up Exercise Generator

Suggests a dynamic warm-up movement — arm circles, leg swings, walking lunges and similar moving stretches — for the few minutes before a workout properly starts.

Seed (optional)

The same word, at the same settings, gives the same result. It goes into the address when you generate, so a copied link opens with the word in the box. A seed is for repeatability, not secrecy.

What this generator does

Draws from movements meant to prepare the body rather than fatigue it, which is a genuinely different list from the training generators — a warm-up that leaves you tired has failed at its job.

What you'll get

This generator draws from a hand-checked list of 10 entries. Here is a spread of 6 of them, so you can see the style before you generate:

Arm circles, forwards and backwards
Leg swings, front to back
Walking lunges
Hip circles
Ankle rolls
Standing toe touches

A fixed sample of the list, not a live draw — your own results are picked at random from all 10, without repeating until the list runs out. Original HEKNO-curated dynamic warm-up list. Last reviewed 2026-07-25.

How to use this tool

Press generate for a warm-up move.
Generate a few in a row to build a full warm-up.

Understanding the controls

Seed: A typed word rebuilds the same warm-up movement from the ten dynamic options on the list. Once you draw, the word is in the address as well as the box, so a shared link brings it along and the same movement comes back on the button.

Worked examples

A generated move: Arm circles, forwards and backwards — one of ten dynamic movements the list draws from.

Common use cases

Building a pre-workout warm-up routine
PE lesson warm-ups
Injury-prevention prep

Limitations and good to know

These are dynamic, moving stretches rather than the held static stretches on the stretching generator — the two are not interchangeable before a session, since a long static hold before intense effort can temporarily reduce power output.
No duration is set. A warm-up that takes thirty seconds and one that takes ten minutes are both valid depending on the session ahead; the movement alone doesn't decide that.
It does not target what a specific session will load. Pick moves that rehearse today's main lifts rather than drawing at random if you know what you're about to do.

Practical tips

Warm up the areas the session will actually load rather than doing the same routine regardless.
Build gradually. A warm-up that starts at full intensity is the thing it was meant to prevent.

Entries are chosen with your browser's cryptographic random number generator, so every entry on the list is equally likely. How Generate Random works.
