hahaha.
becoz i have high metabolism, i cannot grow fat even if i dun
exercise for one month and eat alot.
haha.
but for me building up six pack is no big deal too.
i always see my dad doing sit ups and laugh at the idea coz unlike
him i dun need to use much effort to get one.though rite now i its
less chunky coz i'm abit lazy.
haha.
gud luck
