Something that I have noticed lately is a very strong ammonia smell coming from my t-shirts after training. Normally I take my t-shirt off straight after my training session and dump it into my gym bag. When I take the t-shirt out the next day (yes I know I should take it out as soon as I get home but that would require some thought on my part but hey it gives you a bit of a headrush as the ammonia smell hits you and it doesnt cost anything) it just wreaks of ammonia. Anyone know why there would be such a strong smell?
