If you do get endorphin rushes from it, I hate you and want to be you.
I don't get endorphin rushes from running, except maybe once every few months when I'm particularly fit. I wouldn't say it's enough to keep me going, not even a little.
But I do feel better, generally, when I exercise regularly. I am a happier person in my life if I get some exercise, and between that and my sister waiting for me three times a week, that's enough to get me out the door.
I am amazed that, even unemployed, I got up at 5:40 AM today to go running. But if I don't, my sister probably won't run either, and I shouldn't punish her for my bad job luck.
The only endorphin rush I've ever felt was having a baby. That was like drugs.
I like exercise in that I feel good afterwards but there's no rush feeling.
I think I've had an endorphin rush from exercise like, once. At Krav Maga. But since I've also had an ASTHMA attack like, once, also at Krav Maga...well.
I don't get endorphin rushes from swimming. Just a mellow reserve. Thank goodness, because there is a thin line for me between a fun high and a not fun high energy. I'm running red in the not-fun high of late. Crazy getting-done, but oh god. Everything in my body revolts.
Right now I'm getting my exercise by moving things around as I pull out things for the Goth - Steampunk rummage sale I'm vending at this weekend.
Also, someone please remind me in a month or so that I REALLY don't need to buy any more lace, fishnet, or open-weave hosiery unless I find an amazing pattern in burgundy or gray. I am All Stocked Up on black (and glittery black) versions of such things.
I get a high from a long yoga session, but I think that's partially due to the breathing and the twisting releasing random crap from my muscles. I do not get a high from running, even when I run 5 times a week, but I embody crankiness if I don't run.
The only endorphin highs I've ever had were from deep massage and acupuncture/pressure. Not exercise.
Endorphin highs happen from tattoos. That's about it.
Hmm, I should reconsider my lack of tattoos.
