good post. I concur they did little for me as I feel it did me worse when I did this for a 4 week prep I call bullshit on them. we used goggles and a snorkel but same dam thing maybe I didnt approach it well enough but I found no edge in my cardio in fight allthough I did lose to much weight before fight doing this
