About Body Fat Test California

Body Fat Test California brings lab-accurate hydrostatic body composition testing directly to gyms, studios, and businesses across Los Angeles, San Diego & Ventura. Our mobile testing trucks carry a warm, private dunk tank — the gold-standard method for measuring body fat without any radiation.

Led by Linda Finley, our team has tested thousands of clients — from first-time testers to competitive athletes, trainers, and corporate wellness programs. Every test takes about 10 minutes and comes with a detailed printed report: your true fat and fat-free mass, personalized calorie targets, and your full testing history for tracking progress over time.

If you’re not testing, you’re guessing. Find a truck near you and jump in.
