Occlusion training - might shed some light
I remember reading up on this ages ago during my study/training - occlusion training has shown to be an effective method for gaining muscle size. There are different theories, along the lines of inhibiting oxygen to stimulate fast twitch muscles, and helping the muscle pool the growth hormones released in the exercised muscle - I presume the latter might have something to do with PE.
Anyway there have been numerous studies showing positive results for gaining muscle size by putting elastic bands at the top of the muscle, and on this forum putting a ring or elastic band on your dick has been condoned by many - is there a link?
I did a quick search on this forum and found no threads on this, so apologies if this has been mentioned already. If not - please, fellow researchers, prove me wrong or accept this theory.
