Right after  receiving these boxer briefs, I headed for the gym and spent an hour lifting weights and working on the elliptical machine.
These boxer briefs are absolutely great!!
They are soft, very comfortable, hold your "package" in place and they will not crawls up your legs.
Having said that, I highly recommend them only to people that are in reasonably good shape and without an oversized gut adorning the midsection.
Due to the fact that they are NICE and tight, and I repeat the word NICE, I can see that they would be a bit tight on overweight people.
Sorry...but I only give honest reviews.
