Not all sweat is created equal

I've done the gym thing, the Aerobics DVDs, Yoga, Pilates, and other various fitness activities, but nothing beats running. I know that sounds weird, and if you know me, it sounds even weirder coming from me. However, the one thing that I've found is that through all those activities running actually makes me feel like I've earned that sweat. Yes, I know that sounds disgusting. I hate sweating at the gym, and more often than not, I don't really think I worked hard enough to sweat much at all. Running is completely different, I totally worked hard enough to sweat, and I don't mind it, because I think it reminds me how hard I worked. lol I know this is totally crazy, but oh well. :)
