During the The Daniel Plan Fun Walk & Run on June 11, you might want to bring a towel and swim suit so you can get dunked, and we’re not talking baptism.

One of our proud sponsors, the 12 Week Fitness Challenge has arranged to have a water tank available, thanks to FitnessWave, to help you get an accurate body fat measurement. So we asked Joshua Boyd, owner of 12 Week Fitness Challenge to tell us more.


As body fat testing, rather than simple scale weight, has become “the standard” in this new millennium, Hydrostatic Testing (Underwater Weighing) has become universally regarded by industry experts as the “Gold Standard” in body fat testing. Renowned author and fitness expert Covert Bailey, in the phenomenal best seller “Fit or Fat,” states “That hydrostatic testing (underwater immersion) is the most accurate method for body fat determination.”

The fact that bone, muscle, and connective tissue collectively known as lean mass sinks, while body fat floats is the main principle behind (hydro-densitometry) hydrostatic testing. By obtaining your land weight and water weight (based on buoyancy), our specialized computer program can scientifically calculate your body fat as a percentage of your total weight.

Clinically speaking, the hydrostatic testing method has been around for over 50 years and is based on Archimedes principle which states “that when a body is submerged in water, there is a buoyant counter force equal to the weight of the water which is displaced.” Again, because bone and muscle are denser than water, a person with a larger percentage of lean body mass will weigh more in the water and ultimately have a lower body fat percentage versus someone with less lean muscle mass. A person with more body fat will lighter in water. Body fat floats and lean tissue, muscle, connective tissue, bones, etc.


According to research, “Hydrostatic Body Fat Testing “is still the “Gold Standard” to which all methods of body fat testing still compare themselves. FitnessWave has been the pioneer in hydrostatic testing for over 11 years. We strive to provide accurate and affordable hydrostatic testing to our clients with a professional touch. Fitnesswave makes hydrostatic body fat testing a fun experience for the whole family. So come and get dunked today!


According to Boyd, getting dunked helps measure your current and future physical condition and establishes a goal for the 12 Week Fitness Challenge.

“We feel that people put too much focus on weight loss and not focus on Fat Loss! So we incorporate the “Dunk” so that we can target a certain number of Fat pounds and teach each Challenger what a realistic amount of FAT that can be lost in those 12 weeks — if they follow the Nutrition and Fitness plans we provide,” he said.

“We educate people to Keep the Muscle & Burn the Fat! This way people have a positive approach and don’t just focus on the scale. The true test is how they feel inside and how they look in the mirror!

“When exercising the correct way we can teach people to target the body’s fat deposits. When you combine this with the proper nutrition and eating foods that assist in burning fat, our challengers achieve results they never thought they could achieve!!!”

  6. Wear something snug fitting that does not trap air
  7. Board shorts not recommended
  8. Spandex or cotton workout shorts recommended for guys
  9. No cardio 30 to 45 minutes prior to dunking


During test:


  1. Relax in the tank
  2. Listen closely to fitnesswave tech on details on testing procedures
  3. Get any trapped air out or trunks if any
  4. Take a few deep breathes before going under (oxygenate the blood)
  5. Blow a majority of your air out prior to going under
  6. Finish off blowing as you go under
  7. Use your diaphragm to push out any remaining air
  8. Keep body on rack with elbows close to side (close grip pushup position)
  9. Once out of air stay still under the water until the FitnessWave tech taps your shoulder
