Baseball Rotational Velocity

Eight weeks of hip-to-shoulder separation and back-leg drive for hitters and pitchers who want bat and ball speed, not just weight-room numbers.

How to run it

  • Rotation is a ground-up event. The hands finish what the back foot starts, so every session opens with a lower-half drill before anything rotational.
  • Track both sides. If your dominant side out-throws the other by more than 15 percent, spend an extra set on the weak side all block.
  • Keep hitting volume as it is. This block adds three short sessions, it does not replace practice.

Springbak® note

Rotational power is limited by how well the back foot holds the ground. Install Springsoles under your cleat insoles in week 1 and keep them in through the week 8 retest so every exit-velocity number is set on the same platform.

The goal

Add 3-5 mph of exit velocity by improving ground force through the back foot and sequencing into the swing.

How it progresses

  1. Phase 1 · Weeks 1-3

    Positions: pelvis-first sequencing, slow medicine ball work, single-leg strength.

  2. Phase 2 · Weeks 4-6

    Speed: rotational throws at full intent, loaded jumps, heavier back-leg work.

  3. Phase 3 · Weeks 7-8

    Transfer: overload/underload bat work, volume cut by a third, retest in week 8.

What you test

Exit velocity
Five swings off a tee, same ball and bat. Record the average of the top three.
Rotational med-ball toss
8 lb ball, side toss for distance. Best of three per side — compare left to right.
Broad jump
Best of three. A clean read on how much force the lower half is producing.

What you need

  • Medicine balls (4-8 lb)
  • Open wall or net
  • Barbell or trap bar
  • Radar or exit-velo device

Questions about this block

Is this for pitchers too?

Yes. Pitchers run the same sequencing work; replace the bat-speed transfer drills in phase 3 with weighted-ball work your pitching coach already prescribes.

Can I run it in season?

Cut to two days a week and drop the loaded jumps. The medicine ball work is low fatigue and can stay year round.

Off-season · Nothing to protect on the weekend, so this is where the heavy, high-volume blocks belong.
