Can I just say that I love this exercise?! It can be done virtually anywhere, leaves your hands unused and clean, and feels great while you are doing it! I tip my hat to Fow, the creator (if I am not mistaken) for devising this great tool.
Any insight from the collective on this? I am a newbie and doing PE for less than a week now but I have been doing it all day (not constantly) and some of yesterday.
Will this largely only impact flacid length?
