Until now, hydrostatic body fat testing was only available at a few universities. Now we are bringing it to Willow Bend Fitness.

Totally submerge yourself in water with your nose and mouth just slightly out of the water. You need to bring a swimsuit and a towel. No T-shirts or loose clothing should be worn. We have a private dressing room on board. The test takes 10 minutes and you will be underwater for about 5-7 seconds.

For your comfort the lab is air conditioned in the summer and heated in the winter. The water is heated to between 89o and 94o, depending on the season. The water is chemically treated for cleanliness to meet all local swimming pool and hot tub requirements of the local health department.

Eating within 2 hours before the test may affect your results by up to 1 1/2%. Therefore, we advise you not to eat within two hours before the test. Working out and drinking water is okay. You should try to use the restroom and take a shower if possible.
