משהו שמצאתי:

Like the shoulders, the triceps also are a three-headed muscle complex. While complete isolation of each head is not possible, you can shift focus to either the long head, or the short and medial heads, by varying your arm position. Maximal stimulation to the long head (the lower most portion of the back of the upper arm) can be achieved by bringing the arms overhead in exercise performance. Consequently, exercises such as overhead rope extensions and overhead dumbbell extensions will exert the greatest amount of stress to this area of the muscle. Alternatively, as you bring your arms down and close to your body, the short and medial heads increasingly active in the movement. Hence, exercises such as triceps kickbacks and triceps pushdowns work these portions of the triceps more directly.

בקצרה בעברית:
אי אפשר לבודד כל ראש לגמרי, אבל תרגילים שבהם היד מעל הראש יתמקדו יותר בראש הארוך.
תרגילים שבהם הידיים קרובות לגוף יתמקדו יותר בראשים האחרים.
