Swim Pull Drill

An arms-only freestyle drill that isolates the catch and pull so the underwater stroke can be rebuilt.

How to do it

  1. Push off in a streamlined position with the legs quiet and the body long.
  2. Enter one hand about shoulder-width apart, moving forward and slightly down, with the palm flat.
  3. Set the catch by dropping the hand down and in while the elbow bends and points out to the side.
  4. Press the hand and forearm straight backward as one surface, accelerating as the hand passes under you.
  5. Finish the stroke just past the hip, thinking back and up rather than pulling straight through.
  6. Recover the arm forward while the other side repeats the same sequence, keeping the legs still.

Key technique cue

Elbow above the hand, press straight back — not sideways.

Common mistakes

  • Entering the hand too wide or too narrow, which compromises every phase that follows.
  • Rushing the catch and overpowering it, so the arm never gets oriented backward for the pull.
  • Sculling side to side instead of pressing straight back, which moves water sideways rather than behind you.
  • Dropping the elbow below the hand, a position linked to painful shoulders in competitive swimmers.

Benefits

  • Isolates the catch and pull so hand path and elbow position can be corrected without leg compensation.
  • Loads the main propulsive muscles of freestyle, which contribute the majority of forward force.
  • Builds upper-body endurance in a non-impact environment with no external load.

About the exercise

A pull drill removes the legs so the underwater arm stroke can be worked on its own. The hand enters about shoulder-width and slightly downward, then the catch drops the hand down and in while the elbow bends and points out to the side. From there the pull presses a large surface straight backward with increasing hand speed, and the hand exits just past the hip. The muscles follow that sequence. Early pull-through is driven by pectoralis major, and late pull-through brings latissimus dorsi in to extend the shoulder. Pectoralis major, latissimus dorsi and teres major are the main force producers across this phase.
