In-Depth Analysis of Breaststroke Pull Technique: Pull Arc and Push Timing

Introduction

The arm pull of the breaststroke is the most rule-complex stroke among the four competitive swimming strokes. The rules require both hands to perform identical movements simultaneously, and the entire process from the push phase to the forward extension must be completed below the water surface (except that the hands may briefly break the surface at the moment of breathing). However, beyond the rules, the breaststroke pull involves precise mechanics: an overly wide sweeping arc wastes energy on drag, pulling the hands in too early during the push phase forfeits acceleration opportunities, and a slow forward extension leaves the body stalled in the water. This article will break down the technical details of the breaststroke pull step by step, from entry, outsweep, insweep, push, to forward extension.

Entry and Outsweep

The breaststroke pull begins from a streamlined position with the arms fully extended forward. Before starting the outsweep, the hands are in a “praying” position or extended forward in parallel.

Key points of the outsweep:

• The palms rotate outward (thumbs pointing down) and begin to spread to the sides
• The outsweep width should not exceed 1.5 times the shoulder width; an overly wide outsweep creates excessive drag
• The outsweep speed should not be too fast; this phase is mainly about “finding the feel of the water” to prepare for the subsequent pull
• The elbows begin to bend slightly, preparing to transition to driving backward

The outsweep phase is the stage of the breaststroke pull with the greatest drag and the least propulsion. It should be passed through as quickly as possible without pausing.

Insweep and Pull

After the outsweep reaches its widest point, the palms rotate inward (thumbs pointing up) and begin a powerful insweep. This movement sweeps the palms and forearms from the outside inward, downward, and backward, and is the primary phase where the breaststroke generates propulsion.

Key technical points of the insweep:

• The elbows bend further to approximately 90–120 degrees
• The palms remain vertical or slightly angled backward so the water “hangs” on the palms
• The sweeping path is an inward and downward arc, not a straight line backward
• The elbows should not come too close to the body; most of the insweep should be completed in front of the body

Push and Forward Extension (Recovery)

After the insweep ends, the palms continue pushing the water backward and downward until the hands nearly come together beneath the chest. At this point, a distinct reactive force from the push should be felt.

The critical timing of the push:
Many beginners rush into the forward extension before the push is complete, needlessly losing the propulsion from the final segment. The correct push should continue until the hands reach directly beneath the chest and the elbows are nearly fully extended, only then transitioning into the forward extension.

Key points of the forward extension:

• After the hands come together in front of the chest, immediately extend them rapidly forward
• The forward extension is synchronized with the end of the kick, allowing the body to glide in a streamlined position
• Do not pause too long after the forward extension; begin the next outsweep as soon as the gliding speed starts to drop

Breathing Integration

Breathing in the breaststroke occurs at the moment the hands perform the insweep and the face naturally lifts. The timing of the breath is coordinated with the insweep motion, allowing the head to rise naturally. After inhaling, the face submerges in sync with the forward extension. During the breath, do not lift the head too high (the chin should not rise above the water surface) to avoid increasing body drag.

Practical Tips

1. Practice the rhythm of “slow outsweep, fast insweep”: During technique drills, deliberately slow down the outsweep to feel its drag, then accelerate the insweep to establish the correct rhythm of force application.
2. Use a pull buoy to isolate the arms: Hold a pull buoy between your legs to keep them fixed and practice only the arm pull, making it easier to feel the water at each stage of the pull.
3. Check your elbow position: When swimming breaststroke, have someone observe your elbow position from above the water to ensure your elbows do not come too close to your body too early during the insweep.
4. Coordinate with the kick: In the full breaststroke, the kick should begin after the forward extension, not during the push, to ensure the body’s undulation and the arm pull rhythm are coordinated.

Conclusion

Improving the breaststroke pull requires a clear understanding of each stroke phase and extensive deliberate practice to build muscle memory. In particular, the timely forward extension after the push and controlling the width of the outsweep are key breakthrough points for many intermediate swimmers looking to improve their technique. With consistent practice and regular video analysis, your breaststroke pulling efficiency will improve significantly.
