uli variations

When doing a uli, i read about people pumping five times, holding a squeeze for thirty seconds, squeezing five times, what is the difference between these different uli’s and which is best for which type of gain?

Uli’s are primarily for girth. Guys invent these different variations to come up with something that works best for them and everyone is different. Try them all, invent some of your own. You will be the best one to pick which seems to provide the best workout for you. It’s all about pumping it up and maintaining a lot of internal pressure.
