The one I bought costed me about $20, so it isn't the biggest investment, and just for the sake of fun, it is actually quite interesting. And it would be cool to see what data it would give for you, considering that you are very fit, big muscles, and little body fat! :)

Once again, it is mostly about having fun for me and to see how it will improve or give me worse data over time. Thanks for letting me know your thoughts and giving me your feedback on the subject!
