What is a Commit Block in Volleyball? And Why It is Important

In the fast-paced, high-energy game of volleyball, effective blocking is critical for turning the tide in favor of your team. While the skill of spiking often steals the limelight, a good block can be just as electrifying and game-changing. One specialized form of blocking that requires both skill and strategy is the “Commit Block.” This article aims to explain what a commit block is, why it is important, and how to master this technique to optimize your game performance.

What is a Commit Block?

A commit block in volleyball is a specialized type of blocking where the blocker fully commits to stopping a particular hitter, regardless of other potential threats on the opposing side. In contrast to read blocking or swing blocking, where the blocker reads the set and adjusts their position accordingly, commit blocking requires that the blocker decides in advance which hitter they will focus on. The blocker then fully commits their energy and attention to blocking that single attack, disregarding other attacking options that the opposing team might have.

Why Use a Commit Block?

The commit block is a high-risk, high-reward strategy, and it’s not applicable in all situations. Here are some scenarios where a commit block might be beneficial:

  1. Predictable Offense: If the opposing team has a particularly strong or predictable hitter, using a commit block can neutralize their impact on the game.
  2. Late-Game Strategy: During crucial moments in a match, when a key player on the opposing team is likely to be targeted for an attack, commit blocking can be a game-changing tactic.
  3. Mental Edge: Successfully blocking a star hitter with a commit block can be a psychological blow to the opponent, possibly affecting their performance for the rest of the match.

Key Techniques for Mastering the Commit Block

Mastering the commit block requires both physical skill and mental acuity. Here are some key techniques to focus on:

Pre-Block Preparation

  1. Scouting: Knowing the tendencies, strengths, and weaknesses of your opponents is crucial for successful commit blocking. Understanding who the key hitters are, what their favorite shots are, and where they like to place the ball can inform your decision to commit.
  2. Communication: Before the serve, communicate your intention to commit block so that your teammates can adjust their defense accordingly.


  1. Timing: Timing is crucial in commit blocking. Initiate your jump as the hitter is about to make contact with the ball, not when the setter makes the set. Poor timing will result in either a missed block or a tooling off the block by the hitter.
  2. Hand Position: Your hands should be firmly pressed over the net, aiming to take away the hitter’s preferred angle. Make sure your fingers are spread wide to cover more area and are positioned over the net rather than beside it.
  3. Body Alignment: Your shoulders and hips should be square to the net. Being twisted or turned can result in weak blocks or channels for the ball to pass through.
  4. Eye Sequencing: A good blocker watches the ball, then the setter, and finally the hitter in a quick sequence. This helps to anticipate the trajectory of the spike.

Post-Block Adjustment

  1. Quick Recovery: Whether successful or not, a commit block requires quick recovery for the next play. Train to land balanced and move quickly back to your base position.
  2. Review and Adjust: After the play, quickly review what went right or wrong and adjust your strategy accordingly.

Practice Drills

  1. Isolation Drills: These drills involve only the setter, hitter, and blocker, focusing solely on the blocking technique against specific types of sets and hits.
  2. Live Game Simulation: Practice commit blocks in scrimmage or game-like situations to better understand the timing and strategy involved.


Commit blocking is a specialized, high-risk strategy that can pay off significantly when executed correctly. It requires excellent timing, precise hand and body positioning, keen observational skills, and strong communication among teammates. With proper training, scouting, and in-game application, mastering the commit block can provide a formidable defense against even the most potent offenses.
