Spatts ...I am thinking about the hair scenario and almost clutching my chest in an re-enactment! Poor thing; I feel for you.
I feel almost reluctant to do it again since I had not mastered the breathing thing. They had instructed me not to blow out until under -- and I just could not get to that spasm point you speak of -- I think my mind took over and just could not mentally get there. My husband is nearly a pro at it but I do know he talks of the chest thing....so I know I am missing the boat on this.
I am guessing since I am not a competitor nor athlete -- I really should not make myself nuts about it. My first test, which was 2 years ago was about a year into training, was 40 years old, 5'7 at 135 pounds and was at 29.6% bodyfat -- I was depressed for a week! I had figured my bodyfat was about 24-25%.....given that I could not do the hydro the right way -- I am sure their results were not skewed by more than a percent or two -- which still left me with 27.5% -- blah!
Today, I have not gotten on a bodyfat scale nor used calipers ever in my life.....from eyeballing, a few competitors and their coaches tell me I am most likely about 20% -- I am no expert so I cannot say...
I know little of bodpods....how is it different from the magnetic body imaging that can now be done -- or is it that same thing?
