Also 275lbs fat is a bigger person than 275lbs muscle since muscle is much denser. Also the weight of blood in a fat person is more than the weight of blood in a muscular person. Plus, lots of fat floating around stuffing things up.
The moral is of course, train everything. [/quote]
It is actually only 20% more dense. 
Not really alot imo.

Most experts would consider muscle tissue much denser than fat. That is why they determine body mass index (and percent of lean body mass) by body weight in water (fat floats and muscle, bone, etc donât).

There are basically two types of cholesterol, Low Density and High Density. Current thinking is that the overall cholesterol level is not as important as the ratio of low to high density (lipoproteins). You want to increase the high and decrease the low.
Exercise has been shown to do just that. Dietary habits also affect this ratio, but not to the same extent.
Also, understand that genetic factors do play a role. Your body actually needs and produces its own cholesterol even if you donât eat any. So cholesterol is not bad; just too much is bad.
So aside from any genetic factors, most people can maintain healthy cholesterol through exercise and diet. Primarily aerobic exercise improves the lipoprotein profile. I havenât seen many studies that show weight training improving cholesterol, but I havenât checked in a while
Yeah, but what I thought was then some of the big guys eat 5000 calories a day, and there is alot of red meat and eggs etc, they will indeed get much more cholesterol than a normal guy eating 2000 kcal a day. Is that bad? Is my thinking here flawed? 
I understand that. But I thought that the current views had shifted in the medical community to be less dietary and more activity based than was once thought. Per se its ok to eat eggs as long as youâre getting exercise.

Itâs more complicated than just eating a lot of cholesterol. Cholesterol is bad in some people, because due to other factors, their body takes the excess cholesterol and deposits it in arterial walls causing blockage or narrowing of the artery. This is not just limited to the heart. It could occur in any artery, including those supplying the penis. Yes, that is why some guys canât get it up.
But the key thing here is that high cholesterol in itself does not cause these plaque formations. It is only one factor.
In any case, I donât think the average guy who eats meat and eggs will have any problems as long as he exercises and eats other healthy foods such as whole grains and vegetables.
A good example of this is the Atkins diet. Even though the diet consists of low/no carbs and all meat, eggs, cheese, etc., it doesnât typically raise cholesterol levels in people who are not genetically predisposed to high cholesterol.
For example: USATODAY.com - Study: Atkins diet good for cholesterol
So in reality, eating cholesterol is not as bad (for most people) as many have stated. Itâs the other factors like exercise and diet factors that play a bigger role.
And the moral of the story?

It is not so much the LDL that is bad, its after the LDL gets disoriented through oxidation or glycation. Which is a major reason smokers and twinkie lovers have higher cholesterol (in many cases) than healthy meat and fat eaters. This damage done to LDL causes them to deposit their cholesterol stores into the walls of arteries causing atherosclerosis.
If you have healthy little LDLs depositing triglycerides into your tissues(for energy), then it should be in sync with your HDL removing cholesterol from your tissues and back to your liver for elimination. No damage done there.
As long as you give you tissues a reason to use energy and eat healthy (low carb, high protein, moderate fat) than you should do alright as far as your cardiovascular health goes.

Yes. This one of the reasons why it is so important to get some powerful antioxidants in you or a regular basis.
Oxidised LDL or VLDL acts as a chemical attractant for macrophages (a wandering cell that scavenges material that shouldnât be there) to come and try and engulf the LDL.
The macrophage becomes bloated and unable to move, due to the huge amounts of LDL it has to consume. The macrophage then becomes a âfoam cellâ, taking up space between the artery inner surface and the muscular middle wall of the artery.
This contributes even futher to the narrowing of the artery.
So, look for a high ORAC rating on your antioxidants like acai, goji, resveratrol, mangosteen, etc.

This might be a stupid question, but what is an ORAC rating? And what is considered a high or good rating?
can your ldl levels be too low? Are they useful for anything?

One AHA statement on resistance training from July 16th 2007 can be found online in Circulation.
In summury, it concludes that resistance training (weight lifting) induces symetric physiological hypertrophy of the heart, with slight reduction in blood pressure in the younger population
( acute RT increases blood pressure, more so when approaching 80%+ of 1RM) with some increase in main artery stiffness (such as the aorta)
probably to mitigate the effects on acutely and severly increased BP when doing heavy RT. Some benefits in body compositions/dyslipidemias.
However, one must be carefull because this statement, summerizing a number of studies and reviesw does not necessarily apply to people who go on to put ââvery significantââ muscle mass on their frames
(you know, the 5â5ââ 250 lbs bodybuilder)
considering that most studies tend to use moderate weightlifters or ââvirginââ lifters put on a training regimen with pre and post intervention evaluation.
From that stand point, I think it would nothing short of arrogance mixed with ignorance to argue one way or the other in terms of what happens at the ââexcessiveââ end of the weight lifting spectrum.
Most of us are nowhere near that point anyways.

LDL is important. LDL transports triglycerides and cholesterol from our liver to our tissues. If our tissues could not get cholesterol then our cell membranes would become more rigid, as cholesterol maintains the fluidity of cells. Also triglycerides are used as energy by our body. Some recent studies have shown very low cholesterol levels to be a cancer risk, but then again what isnt a cancer risk?
Come to think of it, testosterone is cholesterol based, does this mean that it is transported through our blood stream and to the target tissues via LDL?
Testosterone has a cholesterol based structure but it is transported in plasma by albumin and TeBG (Testosterone binding globulin) in a ± 55 vs 45% ratio.
Cholesterol in cell membranes helps maintain a certain level of cell membrane fluidity, it decreases fluidity at high temps et reduces at lower temps.

Good post.
Also, certain types of bacteria have been linked to increasing the plaque formation in arterial walls, namely the bacteria that is found on your teeth. A good reason to maintain good oral health, not to mention that no babe wants to kiss someone with bad breath.

OK, so the question that I was leading up toâŠ
I had my Cholesterol check a while back when I gave blood and my Total was 74. My HDLâs were in the 60âs I donât remember how hi. So would that mean anything other than I just need to have it checked again?

Total cholesterol 74? That canât be right. Donât you mean your LDL was 74 and your HDL 60?
And if this is true, that is very good.
