Gyms can be a hotbed of funky smells, unidentifiable liquids, and icky germs, so it's understandable that you think you need an extra-strength soap for your post-workout shower. While showering is definitely a good idea, it turns out that it doesn't really matter what you use while you're in there. There's no particular ingredient in most "fitness" body washes that you won't find in regular ones—just a higher price tag. Plus, many gym soaps are anti-microbial, and while killing germs sounds like a good idea
, overuse of these soaps can lead to even worse infections.
Rob Dunn, of Scientific American, explains, "Most people who use antibiotic soap are no healthier than those who use normal soap. And those individuals who are chronically sick and use antibiotic soap appear to get sicker [than those who use normal soap]."
Do you need it? No, not only do these soaps not get you any cleaner than regular soaps, if you are using the anti-microbial varieties (look for "triclosan" in the ingredients), you could be doing yourself more harm than good.
