Want to add muscle mass and power this offseason without compromising your athleticism on the field? Packing on lean muscle takes time and requires strength and power-focused training, not just bodybuilding-style workouts.

Simply doing 3-4 sets of higher reps may build size, but won't effectively develop the dense, force-producing muscle fibers baseball players need. The key is training for myofibril hypertrophy through lower-rep, higher-intensity lifts that build contractile strength over time, not just sarcoplasmic hypertrophy that increases fluid and glycogen storage capacity.

Let the hypertrophy come as a byproduct of properly programmed baseball power training. Focus on speed, power, and strength first through multi-joint, compound lifts using periodization, then add supplementary muscle-building work. Control volume and fatigue so your nervous system can keep intensity high on strength days.

​Proper nutrition also can't be overlooked when trying to gain mass. Make sure you're in a caloric surplus and getting enough protein to support lean tissue growth. Do this while following an integrated, sport-specific plan that develops all physical qualities for baseball success. The grind builds the muscle and power to dominate next season.
