Taken from a Recovery article by Jason Ferrugia at Elite FTS:
"In between the [PWO Meal] and your next meal you could take advantage of another recovery technique known as contrast baths. This involves sitting in ice cold water for 30-60 seconds followed by jumping into hot water for another minute or so and then repeating for a course of about ten minutes. This can also be done in the shower by simply adjusting the temperature. Just make sure to use extreme temperatures. "
I've never heard of this before - is this beneficial to the amateur, beginner powerlifter like me?
