Is there an easy way to calculate body fat percentage without using an expensive machine or measuring wrists, stomach, neck. Etc? I dont have a tape measure otherwise I wouldnt bother making a thread but a lot of free apps make you measure certain parts of your body. I'm 5'8, 130 lbs if that helps. Inb4 cardio fag or manlet. I run 4 to 5 miles a day and I realize I'm short and will never make it. Thanks for any help in advance.
