<p>To the OP: Who cares. Anyone who needs to ask this question is obviously insecure about the athletic validity of what they are doing. Some people don't think gymnastics is a sport. But does it really matter? Gymnasts know it requires phenomenal levels of athletic ability, so I doubt they even give a damn what others think. Others who, I might add, are usually fat messes themselves, in either relative or absolute terms.</p>
<p>Personally I don't think equestrian is a sport because the horse does the bulk of the work while the human hangs on for the ride and wears a cheesy costume. But I wouldn't say it's easy; I did it once and my nuts weren't too happy about it. I love ultimate frisbee and some people don't consider that a sport either, even though it requires as much athleticism as soccer, which I also play. Not that I care, because it really doesn't matter what other people think. Just do what you want and enjoy it. </p>
<p>If someone wants to make fun or has a problem with it just politely tell them to go have sexual intercourse with themself. Often it's just the encouragement they need to mind their own business and stop infringing on your right to enjoy what you like to do.</p>
