Hi there people,
Today when I finished my gym session I thought I'd ask the helper lady to check how I'm going overall.
I've never felt the need to see how I was going, but at the begginning (last September) I was 19.5 percent BFI and I'm not sure how much BMI.

Now I'm 11.5 percent BFI and 20.5 BMI

For a while I've had an idea of getting down to 12 percent BFI and so now I'm actually less than that I don't really know what to do!
I am not satisfied, in that my ultimate goal is to have more noticable abs and offcourse a six pack would be nice

So should I carry on doing about 30-40 minutes Cardio and 20-30 minutes weights?
Maybe push myself more on the weights or something? I feel as if cardio is essential even if I'm not trying to lose weight as it is good for your body overall.
I dunno, what do you people think?
I'd really like everyones suggestions at this stage and it is very much appreciated.
I know I'm probably quite a typical case but a six pack is surely within my grasp now?

Cheers ppl.
Rob.

Also I wondered what the BMI and BFI effectively means considering my age and all the rest of it?
basically just the Implications, like is my weight and BFI/BMI healthy for my age and literally what BMI and BFI is?

Thanks again ppl.
Me.

BMI is useless. ignore this number, always.

a bodybuilder with 5% bodyfat will have a BMI that makes him obese.

a tall anorexic woman's BMI will show she's absolutely healthy.

at 11% body fat, its your decision...do you wanna see washboard abs, or do you wanna throw on a few pounds of muscle first?

Hey Malkore,
thanks for the advice there,
Well I am not keen on "Washboard abs" because to me it just looks skinny and doesn't appear like a sign of strength and muscle.
So what would you recommend I do to throw on a few pounds of muscle?

Also you say "throw on a few pounds of muscle first?" by this are you suggesting I lose some fat afterward?

Cheers mate.

Please has Anyone else got any suggestions?
