Any of you guys ever tried this stuff to speed recovery from workouts? Some of the CrossFit guys swear by these, so I've tried them some (about 5-6 times) lately. I have to say that I can't tell even the slightest difference in soreness, recovery time, etc. I just froze myself half to death and then felt the same! Am I the only one? Perhaps I'm doing something wrong. I tried alternating 30 seconds hot then 30 seconds cold; and just cold for the entire shower. Some of the guys type things like "it all turned around for me when I started taking contrast showers," but I've started wondering if they're using democrat logic, incorrectly identifying a cause-and-effect relationship. They might've just gotten to that point that soreness stops being a constant state of being, about the time they became aware enough to try contrast showers. Also, supposedly folks who do things like take swims in really cold water are healthier. The first thing that crossed my mind was that a physically (mentally--now that's another story!) unhealthy person wouldn't try swimming in freezing water, skewing the stats. Anyway...thoughts?
