To start throwing again after the offseason, build up gradually over several weeks: begin with easy catch at short distance a few times a week, add distance a little at a time, then move to flat-ground throwing, then light bullpens, and only then full-effort pitching. For most young pitchers that takes about 6 to 10 weeks before games. Never jump straight to hard throwing, and stop and see a doctor if anything hurts.
He’s had his real break from throwing, he feels great, and spring tryouts are on the calendar. The temptation is to grab a ball and pick up right where he left off. That’s the mistake. An arm that has rested for two or three months has lost some of its conditioning, and it needs to be rebuilt the same way it was built the first time: gradually.
Here is how to start throwing again after the offseason, step by step, and how to time it so he’s ready before the first game.
“The arm doesn’t remember how much it threw last season. It only knows what it’s been prepared for this week.”
Build it back the way you built it the first time.Count backward from the first game
The easiest way to plan is to start from his first game or tryout and count back. Most young pitchers need roughly 6 to 10 weeks of gradual throwing before they’re ready to pitch in games, with older and harder-throwing pitchers usually on the longer end. If tryouts are in early March, that means easy catch should start sometime in December or January. Starting late and cramming is how arms get hurt.
A typical build-up
| Phase | What he does |
|---|---|
| Weeks 1 to 2 | Easy catch, short distance, 2 to 3 times a week |
| Weeks 3 to 4 | Add distance gradually as the arm feels good |
| Weeks 5 to 6 | Flat-ground pitching motion, easy effort |
| Weeks 7 to 8 | Short, light bullpens, building slowly |
| Weeks 9 to 10 | Fuller bullpens, then live hitters |
That’s a common pattern, not a strict rule. Younger kids may need less time, and anyone who feels tight or sore should slow down. Always warm up fully first (our guide on warming up before pitching covers it).
The rules that keep it safe
Effort comes last
Distance and volume build first. Effort climbs only after the arm handles the work easily.
Small steps
Add a little each week. A big jump in distance or throws is the most common way to get hurt early in the year.
Rest days still count
Throwing every day isn’t the goal. Two or three sessions a week with rest in between lets the arm adapt.
Soreness is information
Normal tiredness is fine. Pain, especially in the elbow or shoulder, means stop and see a doctor.
Use the build-up to groove the delivery
The weeks of easy throwing are the perfect time to lock in any mechanical change from the offseason, because the effort is low and he can focus on how it feels. Smooth is fast. If you don’t yet know what to work on, a free evaluation breaks his delivery down frame by frame and shows the one or two things to groove while he builds back up. Start his free evaluation.
Mistakes to avoid
- Bullpens in week one. The mound comes after catch and flat ground, not before.
- Showcases before he’s built up. Max-effort throwing for a radar gun on an unprepared arm is a common early-season injury. Never trade a healthy arm for a number.
- Two teams at once. If he’s preparing for more than one team, count all of it together.

The bottom line
Starting to throw again after the offseason should look like a slow ramp, not a switch: easy catch at short distance, more distance over a few weeks, flat ground, light bullpens, then full effort, usually across 6 to 10 weeks. Count back from his first game so there’s time, keep effort last, take small steps, and treat pain as a stop sign. Little things now, big numbers later.
Common questions
How long should a pitcher throw before pitching in games?
Most young pitchers need roughly 6 to 10 weeks of gradual throwing after a long break, building from easy catch to flat ground to bullpens before games. Older and harder-throwing pitchers usually need the longer end of that range.
How often should my son throw when starting back up?
Two or three sessions a week at first is plenty, with rest days in between. Adding throwing days and distance gradually lets the arm adapt without being overloaded.
Is it normal for his arm to be sore when he starts throwing again?
Some general tiredness or mild muscle soreness can be normal early on. Pain, especially in the elbow or shoulder, is not. If it hurts, he should stop throwing and see a doctor.
When should a pitcher start throwing bullpens again?
After several weeks of catch and flat-ground throwing, once the arm handles that work easily. Bullpens usually start around the middle of the build-up, light and short at first.
