Just Heat?

Has anyone tried to just heat on a rest day without PE? I wonder if it would be beneficial.

I think the jury remains out on this one.

Some folks talk of red light therapy(NIR) as a way of increasing healing on off days, and comes with some heating.

Some say that heating above a certain temp will allow the collagen in the penis to reform around flaccid length, making gains effectively go away.

Some like hot tubs/saunas and can’t/won’t PE there, but go anyway.

Personally, I think heating on rest days is at best isn’t helpful. Try firegoat rolls or working on game in your off time.
