Every spring, pitchers lose the strength and power they built in the offseason—not all at once, but slowly, as lifting disappears and games take over. Research shows you don’t need much to hold onto those gains, but once training drops to zero, everything starts to fall off fast, and performance and durability go with it. The takeaway is simple: you can scale back in-season, but if you stop training entirely, you’re not maintaining—you’re starting over.
