Why Exercise Daily?

Posted on

The whole “It’s Important To Exercise Daily to Lower Cholesterol” thing is really bugging me.  (Possibly because I didn’t exercise yesterday or today.  No elliptical, no tennis, nada.)  But daily exercise as a goal feels unreasonable to me.  It seems like overkill — I mean why daily?  Why is daily so critically important?

And aren’t I exempt because I’m already in decent shape?

Searching for that exemption led me online, where I found the opposite.  Turns out, there is a concrete reason why exercising daily is important to lowering LDL, no matter what kind of shape you are in (there are probably many reasons, but I can only handle one at the moment.) Here’s an excerpt from WebMD’s “The Exercise-Cholesterol Link.”

“…But recent studies have more carefully examined the effect of exercise alone, making it easier to evaluate the relationship between exercise and cholesterol.Researchers now believe there are several mechanisms involved. First, exercise stimulates enzymes that help move LDL from the blood (and blood-vessel walls) to the liver. From there, the cholesterol is converted into bile (for digestion) or excreted. So the more you exercise, the more LDL your body expels.

Second, exercise increases the size of the protein particles that carry cholesterol through the blood. (The combination of protein particles and cholesterol are called “lipoproteins;” it’s the LDLs that have been linked to heart disease). Some of those particles are small and dense; some are big and fluffy. “The small, dense particles are more dangerous than the big, fluffy ones because the smaller ones can squeeze into the [linings of the heart and blood vessels] and set up shop there,” says Khera. “But now it appears that exercise increases the size of the protein particles that carry both good and bad lipoproteins.”

Which means that if — every day — I’m eating things that produce cholesterol (or my stupid body is over-producing it every single day), then getting daily exercise to remove that LDL cholesterol seems, um, pretty necessary. Because otherwise, that cholesterol has nothing to do but build, right?  Which is how I got here in the first place.

Well, that and Phish Food ice cream.

Is this new learning enough to get me committed to a daily workout as part of my Lo-Co lifestyle?  Not sure yet.  But it does have me thinking about it.
