Building Baseball-Specific Strength: Off-Season Program

Combine power, mobility, and recovery to build an off-season regimen tailored for baseball performance.
A structured off-season plan bridges the gap between the offseason “reset” and the in-season demand for strength, speed, and durability. This 12-week program blends foundational lifts, explosive medicine-ball throws, targeted mobility flows, and recovery protocols to help you swing harder, throw faster, and stay on the field all year.
Program Overview
| Phase | Weeks | Focus |
|---|---|---|
| Foundation | 1–4 | Movement patterns, core stability, mobility |
| Power | 5–8 | Olympic lifts, medicine-ball explosiveness |
| Peaking & Prep | 9–12 | Maximal power, sport-specific strength |
Each week includes three strength sessions, two mobility-focused workouts, and daily recovery habits. Adjust loads by 5–10% every two weeks to maintain progressive overload.
Phase 1 (Weeks 1–4): Foundation & Stability
Key Goals
- Reinforce squat, hinge, and press mechanics
- Build core control and joint health
- Enhance hip and shoulder mobility
Sample Weekly Layout
- Day 1: Back Squat (4Ă—6), Romanian Deadlift (3Ă—8), Plank Variations (3Ă—45s)
- Day 2: Mobility Flow (banded shoulder routines, hip capsule stretches)
- Day 3: Bench Press (4Ă—6), Single-Leg Deadlift (3Ă—8 ea), Pallof Press (3Ă—10 ea)
- Day 4: Active Recovery (foam rolling, dynamic warm-ups)

Phase 2 (Weeks 5–8): Power & Explosiveness
Key Goals
- Develop rapid force production
- Enhance rotational power and deceleration control
- Integrate sport-specific throw patterns
Core Exercises
- Hang Power Clean (4Ă—4): Focus on rapid hip extension.
- Push Jerk (3Ă—5): Train explosive upper-body drive.
- Medicine-Ball Rotational Throws (3Ă—8 ea): Simulate swing and throw mechanics.

Drive the hips and core for maximum transfer of power between lower and upper body.
Supplemental Work
- Lateral Bounds (3Ă—6 ea) for single-leg explosiveness
- Landmine Anti-Rotation Press (3Ă—10 ea) for core stability
- Band-Resisted Hip Thrusts (3Ă—12) for posterior chain strength

Phase 3 (Weeks 9–12): Peaking & In-Season Prep
Key Goals
- Translate strength into sport-specific speed
- Sharpen neuromuscular readiness
- Implement advanced recovery to lock in gains
Peak Power Circuit
- Deadlift (3×3) at 85–90% 1RM
- Box Jumps (4Ă—5) with maximal height
- Rotational Med-Ball Slams (3Ă—8 ea)
- Sprint Variations (5Ă—20 yd)
Mobility & Recovery Protocols
- Contrast Baths: 2-minute cold, 2-minute warm, repeat 4Ă—
- Nightly Mobility: Pigeon stretch, T-spine foam roll, doorway pec stretch
- Sleep Hygiene: 8–9 hours, cool room (65–70°F), blue-light curfew

Tracking Progress & Adjustments
- Performance Log: Record weights, reps, perceived exertion, and any soreness.
- Video Check-Ins: Film lifts biweekly to refine technique and catch drift.
- Load Management: If form breaks, reduce load by 10–15% and reinforce movement quality.
