A good pre-throwing warm-up takes about 15 minutes and moves in order: a dynamic warm-up to raise your body temperature, general mobility to open the hips and shoulders, and a band routine to wake up the muscles that protect the arm. Only then do you pick up a baseball. The whole idea in one line: warm up to throw, don't throw to warm up. If anything hurts during warm-up, stop and see a doctor.
Watch a lot of young pitchers get ready and you'll see the same thing: they grab a ball and start throwing to loosen up. It feels normal. It's also backwards, and it's one of the easiest ways to leave velocity, command, and arm health on the table before the game even starts.
The best pitchers do it the other way around. They get the body and the arm ready first, then pick up the ball already warm. That's the whole difference, and it's the single most repeated rule in arm care.
“Warm up to throw. Don't throw to warm up.”
The ball comes out last, not first.Here's why it matters. A cold arm asked to throw hard is a stiff arm doing a violent, full-speed movement before it's ready. Warming up first gets blood into the muscles, opens up the joints, and switches on the muscles that protect the shoulder, so that first throw comes out of a body that's actually prepared. Structured warm-ups have been linked to meaningfully lower injury rates and even better ball speed. It costs you about 15 minutes and gives you a safer, sharper arm from the first pitch.
| What a warm-up gives you | What skipping it costs |
|---|---|
| Blood flowing, muscles loose and ready | Cold, stiff muscles asked to move fast |
| Hips and shoulders moving freely | Tight joints fighting the delivery |
| The arm's protectors switched on | The arm doing the job unprotected |
| Command and feel from the first throw | Wild, tentative early throws |
The Pre-Throw Primer
This is the exact routine we have our pitchers run before they ever pick up a ball. It builds from general to specific: get the whole body moving, open up the joints, then wake up the arm. Three short parts, then you throw.
Dynamic Warm-Up
Get the whole body moving and the temperature up with athletic movement over about 30 feet each.
General Mobility
Open up the hips, spine, and shoulders so the joints move freely through the delivery.
Band Routine
Wake up the small muscles that stabilize and protect the shoulder and arm.
Now pick up the ball
You're warm and ready. Start throwing easy and build from there.
Here's each part, with the exact movements we use. Move with intent and control, and don't rush any of it.
1. Full Dynamic Warm-Up
Warm-UpMove through each about 30 feet: a light jog, quad pulls and heel scoops, ankle pulls, then a lunge into the world's greatest stretch.
Raise your body temperature and get the whole body moving athletically. Break a light sweat, don't get tired.
2. Complete General Mobility
MobilityAbout 10 reps each: 90/90 hip switches, scorpions, and iron crosses. These open the hips and spine, the joints a delivery leans on most.
Free, easy range of motion. This is movement, not long static stretches you hold in place. Save those for after you throw.
3. Complete Band Routine
Arm PrepAbout 10 reps each with a light band: reverse fly to overhead reach, elevated bicep curls, chest fly to overhead reach, elevated tricep extensions, and internal and external rotations.
Switch on the small muscles that stabilize the shoulder before it does anything explosive. Keep the resistance light. This is activation, not a workout.
Now you're ready to throw
Warm body, open joints, primed arm, and only now does the ball come out. From here your throwing itself becomes the final ramp: start close and easy, focus on clean feel over the lower half, then build distance and intensity until you're at game speed. That throwing progression is its own thing, and our long-toss guide covers how to build it out.
The point of everything before it is that you arrive at that first throw already prepared, instead of using your arm to get ready. That's the whole message: warm up to throw.
How long, and how often
The full Pre-Throw Primer takes about 15 minutes, and every minute pays off in a sharper, safer arm. A few things to keep in mind:
- Do it every time. Practice, bullpen, or game, the arm doesn't know the difference. Consistency is what makes it work. Little things now, big numbers later.
- Save the long stretches for after. Static stretching (holding a stretch in place) belongs in your post-throw recovery, not before you throw.
- Warm-up is not treatment. This routine builds readiness and durability, but it is not a fix for pain. If something hurts during or after, that's a doctor's call. Our guide to arm soreness covers the line between normal and not.
- Pair it with real strength work. A warm-up prepares the engine you've built. Our strength-training guide covers building that engine safely.
The bottom line
Warming up the right way is one of the simplest habits a pitcher can build, and one of the highest-return. Move the whole body, open the joints, wake up the arm, then pick up the ball. About 15 minutes, done every time, for a safer and sharper arm from the first pitch.
A good warm-up gets the arm ready to execute the delivery. Whether that delivery is actually using the body well, or leaking energy and asking the arm to do too much, is a separate question, and it's the one we answer.

How should a pitcher warm up before throwing?
In order: a dynamic warm-up to raise your body temperature (jog, quad pulls, ankle pulls, a lunge to the world's greatest stretch), general mobility to open the hips and spine (90/90 hip switches, scorpions, iron crosses), then a light band routine to wake up the muscles that protect the shoulder. Only after that do you pick up a ball and start throwing easy. Warm up to throw, don't throw to warm up.
How long should a pitching warm-up take?
About 15 minutes for the pre-throwing portion, before you factor in your throwing progression. It doesn't need to be long, it needs to be consistent and done in the right order: general body movement first, then mobility, then specific arm prep.
Should you stretch before pitching?
Yes, but dynamic stretching, meaning movement like leg swings, lunges, and hip and spine mobility, not long static stretches you hold in place. Dynamic movement prepares the body to throw. Long static holds are better saved for after you throw, as part of your recovery.
What should a pitcher's arm warm-up include?
A light resistance-band routine that activates the muscles around the shoulder: movements like reverse fly to overhead reach, chest fly to overhead reach, and internal and external rotations. Keep the resistance light, this is activation to wake the muscles up, not a strength workout, and it takes just a couple of minutes.
Is it bad to throw without warming up?
It adds unnecessary risk. A cold arm making a full-speed throwing motion is asking stiff muscles to do a violent movement before they're ready, which raises the chance of a tweak or strain and usually means worse command early. Taking about 15 minutes to warm up first is one of the simplest ways to reduce that risk.
