i'm a bit skeptical. if this stomach vacuum exercise is so important for this kid, why is everyone not doing it? if this was such a big deal in terms of getting a better midsection, why do i not see every site pushing for everyone to do the vacuum exercise all of the time?
i mean i've heard of it before (never knew it was called the vacuum), but only thought of it as some old school bodybuilders technique for a competition, not something that actually improved your physique. could you enlighten me, i'm really not that knowledgeable of this topic.
