Butterfly - Pull Phase

Most swimmers begin the butterfly pull with straight arms above the shoulders. If the arms complete the entry below the shoulders, they are in a stronger position to begin the pull. If the elbows are flexed as backward hand motion begins, more force is generated.

Two visual cues help master elbow flexion during the pull phase. At the completion of arm entry, see the hands directly in front of the shoulders. As elbow flexion begins, see the hands move to the inside of the elbows. With an optimal head position, both cues are within the swimmer's visual field.
