If you had to choose between the two, which would you use to unsheathe abs. I understand that one is for subcutaneous fat while the other is for VAT but how would you discern? I have read that not being able to perform an ab vacuum indicates VAT, is that true? I'm under the impression that at one point I was pre-diabetic (faaaaat kid).
Would you say I have VAT? I will be doing a log after acquiring either or.
