Every pitcher asks it at some point: should I throw today, or does my arm need a day off? Push too hard and you risk an injury; rest too much and you fall behind. The trick is having a simple, honest check you run *before* you pick up a ball — not after your arm's already barking.
Here's a quick self-check, plus what a real recovery day should actually look like.
The 30-second self-check
Answer these honestly. The more 'yes' answers, the more your arm is asking for rest:
- Is there soreness left over from your last outing that hasn't faded?
- Is any of the ache in the joint — inner elbow or front of the shoulder — rather than the muscle?
- Did your velocity or command drop noticeably last time out?
- Have you thrown hard multiple days in a row without a real rest day?
- Does the arm feel 'heavy,' late, or draggy when you warm up?
Green light, yellow light, red light
| Signal | What it means | What to do |
|---|---|---|
| Green | No lingering soreness, arm feels fresh, mechanics normal | Throw as planned |
| Yellow | Mild leftover soreness or a heavy-feeling arm, no joint pain | Light day: reduced volume, easy catch, or active recovery |
| Red | Joint pain, pain at rest, lingering soreness, or sharp pain | Don't throw — rest, and see a pro if it doesn't clear |
A simple way to read your answers.
What a rest day actually looks like
'Rest' doesn't have to mean doing nothing — for most tired arms, active recovery beats a total shutdown. A good recovery day can include:
- Light band work and shoulder/scap exercises
- Easy mobility and a proper cooldown after your last outing
- Sleep and hydration — the most underrated recovery tools there are
- Gentle catch at low intent, only if there's no pain
Rest isn't falling behind
One well-timed rest day protects weeks of throwing. Skipping it to 'stay sharp' is how a sharp arm becomes a hurt one.
When a day off isn't enough
A day or two of rest handles normal fatigue. But some signals mean you're past 'tired' and into 'get it looked at.'
Stop and see a pro if…
You have sharp pain, joint pain (especially the inner elbow), pain at rest, numbness or tingling, swelling, or soreness that a few rest days don't fix. Fatigue management is not a substitute for medical care.
Stop guessing — track it
The self-check works best when it isn't just memory. If you log how your arm feels and how much you throw each day, the yellow and red flags show up as a trend, not a guess — and you'll rest when you actually need to, not too early or too late.
ArmTrack runs that check for you: log your throwing and soreness in 60 seconds, and it turns the trend into a daily readiness score — ready, caution, or rest. Free for players and coaches.
