The mobile gold standard body composition test without the radiation.

Who runs the lab and where it goes.

The lab comes to you

No clinic visit and no appointment across town.

A private lab on site. The lab drives to health clubs, fire and police departments, universities and workplaces and sets up a warm, private tank. You sit down in it, breathe out and the water does the measuring.

Linda Finley and her team have tested thousands of people that way — first-timers, competitive athletes, trainers and whole corporate wellness programs.

If you’re not testing, you’re guessing.

Meet the founder

Linda Finley

For more than 18 years, Linda has been the owner and operator of Body Fat Test SoCal, a mobile hydrostatic body composition testing service serving communities throughout Southern California.

As a Precision Nutrition Certified Nutrition Coach and hydrostatic weighing specialist, Linda has worked with health clubs, police and fire departments, universities, corporate wellness programs and individuals to provide accurate body composition testing and practical nutrition guidance.

Linda believes in practicing what she promotes. When she’s not on the road testing clients, you’ll often find her staying active, whether she’s cycling, swimming or simply enjoying time outdoors with friends. For Linda, health and fitness aren’t just part of her work—they’re part of how she lives.
