I have to admit: I don't particularly love running. I kind of fell into it when I decided to become a Marine cause they do a lot of it. I got out, got even lazier (that was a feat!), but running's remained my cardio of choice for several reasons.
1. It's free. OK, hear me out on this! Quality shoes - not cheap. A quality bra* - not cheap. But really, once you've got those, you're set. No classes, no membership fees, no certified instructors yelling at you to do 10 more. Just go out your front door and you're at your gym. *Ladies, don't cheap out on your running bras! It's OK to spend a little to treat the girls right. You & your significant other can thank me in 20 years...I maintain a registry at Tiffany.
2. It comes with built-in completion. Say you're at the gym, and you really do not feel like doing that last set of biceps curls. You can just stop and leave. Say you're out for a run and are a mile and a half from your car. You kind of HAVE to finish the route. (Sometimes I see this as a negative...it depends on the day!)
3. It gets itself over with. I am by no means a fast runner. But I would rather run a 5K than walk one any day of the week. Walking takes FOREVER. I even have to confess that lately I've been shortening my walk breaks because I just want to be done.
4. It's at home. I don't have to go anywhere. I hate having to go places. If you didn't know that about me, you do now. I will find a way to make dinner with a can of pineapple, 4 dusty chocolate chips, and a freezer burnt pork chop from 1987 if it will prevent me from having to leave & make groceries. Why add another place I have to go? Especially a place that is, um, 'scented' like most gyms are...ew.
See? All of these combine make running the perfect workout for the less aerobically ambitious among us. That would include me =). So, who wants to go for a run?
