In-Season Training for Pitchers: What Changes and What Doesn't

The most common in-season mistake is stopping. A pitcher spends the winter getting stronger, then quits lifting when games start because he is busy or worried about being sore. By the end of the season, when the games matter most, much of that strength is gone.

In-season training has a different goal from off-season training. It is not about building. It is about keeping what you built and being fresh on game day.

What changes

• Volume drops. Fewer sets and fewer exercises. Sessions get shorter.
• Intensity stays reasonably high. Keeping some heavy work is what holds on to strength. Lots of light reps do not.
• Soreness is managed. New exercises and high-volume work that leave you sore for days are saved for the off-season.
• The week is built around your outings. Training is scheduled from the day you pitch, not from the day of the week.

A starter's week, in outline

• Day after pitching: recovery work, light movement, mobility, arm care. Often the best day for a lower-body lift, since the next outing is furthest away.
• Two days after: catch play, upper-body and trunk work.
• Mid-week: bullpen at planned intensity, lighter lift or mobility.
• Day before: light throwing, movement prep, nothing that leaves fatigue.
• Game day: warm up and compete.

Relievers do not get a predictable schedule, so the rule is simpler: short, frequent sessions, and nothing on a given day that would stop you from pitching that night.

What does not change

• Arm care. Shoulder and scapular work, forearm work and mobility continue all year.
• Throwing with intent between outings. Catch play is practice, not a formality.
• Sleep and food. School, travel and late games make these harder in season, and they are where recovery comes from.
• Tracking. Keep logging velocity and how the arm feels. A steady drop across several outings usually means fatigue or lost strength.

Working with your team

Your school or travel coach sets the game and practice schedule. In-season training has to fit around it, and the team's needs come first on game days. Tell your performance coach when you are pitching and how much, and tell your team coach what you are doing outside practice.

The payoff

A pitcher who keeps training through the season finishes it close to where he started. That is an advantage in playoff games and at summer events, when many pitchers around him are running on what is left.
