Bullpen Routine (Fast-Pitch)
Also known as: pitcher warm-up routine
A bullpen routine is a pitcher's structured warm-up and between-outing throwing sequence, building from short-distance arm circles to full-mound-distance pitches across her full pitch mix.
A consistent bullpen routine serves two purposes: physically preparing the arm and body to pitch at competitive intensity, and mentally rehearsing the pitch sequence and locations a pitcher expects to use. Most routines progress from close-range, low-effort arm circles to build blood flow and range of motion, gradually increasing distance and effort until the pitcher is throwing full-speed pitches from regulation distance, typically working through her fastball first before layering in movement pitches like the drop, rise, curve, or change.
Beyond game-day warm-ups, pitchers also throw regular bullpen sessions between outings to maintain mechanics and pitch feel without the fatigue of full competitive innings. The specific structure of a pitcher's bullpen — how many pitches of each type, how much rest between sets, how it changes leading into a big outing versus a recovery day — is usually built collaboratively with a pitching coach and adjusted based on where a pitcher is in her competitive schedule.
Build your bullpen routine the same way every time so that any mechanical inconsistency you notice is meaningful rather than just a result of a different warm-up that day.
Example
Before a start, the pitcher works through a twenty-minute bullpen routine, beginning with short-range arm circles and progressing to full-distance fastballs, then rise balls, drop balls, and changeups in her typical in-game sequence.
Why it matters
A consistent, well-structured bullpen routine reduces injury risk by properly preparing the arm and gives a pitcher a repeatable mental rehearsal of her pitch mix before facing live hitters.
How it shows up on video
Compare arm circle range of motion and release point consistency from the early, low-effort portion of a bullpen through its full-intensity final pitches to confirm a proper gradual buildup.
Common mistakes
- Skipping the gradual buildup and throwing full-intensity pitches before the arm and body are properly warmed up
- Using an inconsistent bullpen routine from outing to outing, making it harder to isolate mechanical issues when they appear
- Neglecting to rehearse the actual game pitch sequence, leaving pitch selection feeling unfamiliar once the game begins

Frequently asked questions
How long should a pre-game bullpen routine take?
Most pitchers use roughly fifteen to twenty-five minutes, though the exact length depends on the individual pitcher, weather, and how many pitches are in her mix.
