Aided V-Stretch Video
All V-stretches are designed to change the tension gradient within the tunicae, redistributing stress and thus providing greater stress at certain points in the tunicae and lesser stress at other points.
V-stretch modifications generally use an alternate method to provide the secondary force on the shaft. These modifications have come about to improve the level of stress.
This is a V-stretch using some piece of equipment to provide the secondary stress. Many ideas exist for appropriate equipment; they are generally cylindrical and reasonably long. The video shows an Aided V-stretch performed with a padded drum stick but more suitable might be something that under no circumstances is likely to break whilst stretching at high tension e.g. a baseball bat, a length of around 2" diameter PVC pipe or similar. This will impact on the ligaments and the tunica.
