Are progressively heavier weights needed for hanging?

I think that sets that are an hour long are just asking for trouble. Bib suggests 20 minutes; I can handle 30 minutes at a time. But an hour? Not a good idea.

To control blisters I (1) put on a layer of tape, then (2) put about 1/8 tsp baby powder in a silicone cap, and stretch the cap+baby powder over the taped glans. Then I attach the vachanger, and limit my sets to 30 minutes.

I also alternate sets between the bib and the vac hanger, so all the stress isn’t focused on one area. To target the force more effectively, I use a fulcrum. The fulcrum provides a better stretch without adding extra stress on the glans skin.

Once you get a blister, let it heal completely before trying the vachanger again. Then start with lower weight and lower time, gradually working back up to the load you were at before.

Yeah gotta work your way up, the glans will adjust somewhat over time, and technique improves. Switching to water for vac hanging helped my comfort a lot. That and using a sleeve instead of the cone to make the seal. I only ever went up to about 5 - 7 lbs though, and usually more in the 2 - 5 range.
