To the gal asking about body fat percent measuring..there are a variety of ways. Like the OP stated, there's a method where they put you under water and use a caliper. I also heard that there's a method where they measure your neck.
The most common method most people use is a scale. They are not very accurate at all because there's only 2 electrodes, one per each foot and it guesstimate the upper body fat. It helps if you get a reputable brand though, ie Tanita. I use it as a reference point. I'll know when I get down to 9% when my abs become visible, lol.
OP-yeah, man..I'm usually around Burbank and Glendale every day. I go to the 24 Hr Fitness on Brand and California.
