Mid shaft clamping

Why does the “how to clamp” video show the guy start out with a clamp at the base and then later he puts another clamp half way up his shaft?

What does that second clamp do?

Intensifies the clamping pressure on the top half of the shaft and especially the head. Very advanced exercise!

Not only on the top half of the shaft, but on the rest of the un-clamped areas.

Hmmm.. Interesting. I’ve been dry jelqing at higher erection levels for a little over a year now. I’m just looking for the next step.

Clamping in this way is similar to how the horse 440 works, specifically in the area in between the clamps. Both are very advanced exercises and can cause serious injury if done incorrectly.

Holy shit that is intense, I’ve heard of two clamps at the bottom, but not one half way up… My dick would explode.
