Increase Pitching Velocity With One Exercise

Summary

Jeff from Athlean-X demonstrates a resistance band exercise designed to strengthen the shoulder’s deceleration muscles, which are critical for pitchers. The core principle is that a stronger braking system allows you to throw harder — the better you can slow the arm down, the faster you can accelerate it through the throw.

Key Points

  • The braking system analogy: Just like a faster car needs better brakes, a pitcher who can better decelerate their arm can throw with greater velocity safely
  • Deceleration muscles matter: The muscles at the back of the shoulder responsible for slowing the arm down are often undertrained compared to the throwing muscles
  • Equipment setup: Anchor a resistance band low to the ground, approximately one to one and a half feet off the floor
  • Band resistance is critical: The tubing must be thick/strong enough to actually pull your arm back toward the target — if it’s too thin or weak, the exercise won’t be effective
  • Controlled resistance is the goal: The exercise is not about letting the band snap your arm down, but actively resisting and controlling the movement on the way back
  • Mimics the throwing motion: The exercise starts in the cocking position, replicating the actual mechanics of a pitch to ensure sport-specific training

Exercise Details

Exercise: Resistance Band Shoulder Deceleration Drill

  • Target muscles: Posterior shoulder muscles — the decelerators and braking muscles at the back of the shoulder

  • Setup:

    • Anchor resistance band low, about 1–1.5 feet off the ground
    • Use thick tubing with enough resistance to pull the arm back toward the target
  • Proper form cues:

    • Start with arm raised in the throwing/cocking position
    • Jump or step your body back away from the anchor point, loading the band
    • Resist and control the band as it pulls your arm back down — do not let it snap
    • Focus on the eccentric, braking action of the posterior shoulder
  • Common mistakes to avoid:

    • Using tubing that is too thin or weak (eliminates the training stimulus)
    • Letting the band snap the arm down instead of actively controlling the descent
  • Sets/Reps: Not explicitly stated, though 3 repetitions are demonstrated in the video
