Arm care for youth pitchers: a simple before/after routine

Youth pitching injuries are at an all-time high. The American Sports Medicine Institute has been sounding the alarm for years: kids who throw too much, too young, without arm care end up needing Tommy John surgery at ages we never used to see.

The good news: the protocol that prevents most of these injuries is simple, free, and takes 10 minutes.

The bad news: almost nobody in Little League is doing it consistently.

This post is the short version. Print it out, stick it in your kid's bag.

The principle: pitching is a stress action

A pitch — for a 9-year-old or a major leaguer — is one of the most violent things you can ask a shoulder to do. The arm decelerates from 80+ mph to zero in about 25 milliseconds. Repeated stress, repeated recovery.

Recovery doesn't happen by accident. It happens because you do the work.

Before: 5-minute warm-up

The arm gets warm before it throws. Not after.

1. Light cardio (1 minute)

Anything that raises body temperature. Jog the bases. Jumping jacks. The point is to get blood moving before you start swinging the arm.

2. Band work (2 minutes)

Resistance band, anchored to a fence at chest height.

• 10 reps: external rotation (band pulled away from body, elbow at side)
• 10 reps: internal rotation (band pulled toward body)
• 10 reps: scaption (raise band out and up at 45 degrees)

This activates the small stabilizer muscles in the shoulder. Most arm injuries are caused by the big muscles overpowering the small ones — band work re-balances that.

3. Easy throws (2 minutes)

Start at 15 feet. Gentle tosses to a partner. Move to 30 feet. Move to 45. Don't throw with intent — just get the motion moving.

Don't skip this. The single biggest cause of youth pitching injury is throwing hard before the arm is warm.

During: pitch count discipline

The rule is simple: count pitches, not innings. Innings vary wildly. Pitches are the load.

Use these as ceilings — official Little League guidance is similar:

These are ceilings, not targets. If your 10-year-old can throw 60 strong pitches, that's the game. Don't push to 75 because it's "allowed."

And: no pitching when sore. Tightness is normal. Soreness is a stop sign.

After: 5-minute cool-down

The post-pitching window is when the work to recover starts. Don't skip it.

1. Run-out (1 minute)

A slow jog for 60–90 seconds. Helps clear lactic acid from the working muscles. Skip this and the arm is more sore tomorrow.

2. Band work (again, 2 minutes)

Same band routine as before — 10 reps each of external rotation, internal rotation, and scaption. The cool-down version is at lower resistance.

This isn't optional. Stabilizers are fatigued. They need active recovery.

3. Ice (2 minutes, only if needed)

Ice for 10–15 minutes if the kid feels any soreness. Not 30. Not 45. The research has moved away from heavy icing — short cold contact is fine, sustained icing actually delays recovery.

Better than ice: sleep and protein. The kid recovers more from a full night's sleep than from any ice pack.

Warning signs you should never ignore

Stop pitching and see a sports doctor if your kid reports:

• Sharp pain in the elbow or shoulder. Not soreness. Pain.
• A clicking or popping sensation.
• Numbness or tingling in the hand or fingers.
• Decreased velocity over multiple outings. Loss of fastball is often the first sign of a chronic injury.
• Pain that lingers more than 48 hours after pitching.

Any of those = stop. Do not push through. Tommy John surgery on a 13-year-old is not a price worth paying for one season.

The other thing

Most youth pitching injuries don't come from one bad game. They come from year-round, no-rest pitching schedules — Little League in the spring, travel ball in the summer, fall ball, indoor leagues in the winter.

Your kid needs at least 3 consecutive months off pitching every year. The arm is a recovering joint, not a renewable resource. Off-season throwing is fine (long toss, plyo work). Pitching is not.

If you don't enforce the rest, no one else will. Coaches always want one more inning.

The bottom line

A 10-minute routine before and after every pitching outing, a pitch count discipline you actually enforce, and 3 months off per year — that's almost the entire injury-prevention protocol for a youth pitcher.

It's not exotic. It's not optional.
