Wow so I been doin this since I started hanging, but I only do it for the last 2 minutes of my set. In the entire set, it’s the only time that I really feel like I’m puttin work in, and I’m up to 12.5 lbs now. I felt like it would be dangerous, but I always start with small circular swings. Injury of course is very possible, but I don’t know, I think it just depends on the dick. There are plenty of people who have injured their dick just by jelqing, whereas some, like me, have gone years without any injury. I figure that since I’ve been swinging lightly since I started hanging last year, I’ll just continue. Always prepared for an injury though…
