The following article will review an interesting experiment to see how it can be applied to muscle building and penis enlargement.
Muscle Building Research and Its Significance to Penis Enlargement
Research titled “Progressive stretch overload of skeletal muscle results in hypertrophy before hyperplasia” subjected birds to a constant weighted stretch using weights attached to their right wings. Results showed muscle mass increased by 318% in 28 days, while muscle length hit peak increase levels at 60% in just 12 days!
Though the hypothesis of the experiment was to investigate the effects of stretching and resistance in [skeletal] muscle hypertrophy, there are enough physical similarities between skeletal muscle tissue and the penis to see how this applies to PE.
Similarities and Differences of Skeletal Muscle and Penile Muscles
Regarding the similarities: Both the penis and skeletal muscles have ligamental structures, and the fascia of the penis is structurally similar to the fascia surrounding muscle tissue. These tissues respond well to the principles outlined in Davis’ Law. Davis’ Law is a physiological principle that states soft tissue heals according to how it was mechanically stressed. Allowing the tissue to accept the stress during rehabilitation leads to the strengthening of the tissue.
The muscles of the pelvic floor are skeletal muscles- so they do respond to the benefits of combining stretching and contracting. The penis is connected to the pubic symphysis via the penile suspensory ligament. Kegels pull at this ligament in a sling-like manner, as opposed to how a skeletal muscle pulls directly via contraction from the origin to the insertion point.
This is beneficial since kegel exercises help blood flow to the penis. According to Dr. Steven Lamm, author of The Hardness Factor, “Increasing blood flow to the penis strengthens erections and enhances the function of your vital organ.”
Muscle Mass and Penis Enlargement
It’s highly recommended this type of training be reserved for the moderate to very advanced levels of male enhancement training.
Needless to say, this has applications for those wanting to add [skeletal] muscle mass. For those wanting to incorporate fascial stretching into their bodybuilding training, this is best left for the end of training a targeted body part.
