Max climbs into a bod pod at the football training camp to have his body composition assessed. what method does the bod pod use to calculate estimated percent body fat?

The bod pod measures the body mass and the volume to get the body density. Once the overall density is obtained, you can calculate for the relative proportions of lean mass and body fat. 

I hope I was able to answer your question. Have a good day.
