Wondering how many calories I'm expending during exercise.
I'm 5'11, 201 pounds, 20% Fat. I use a HR monitor. I average 123 BPM doing 47 mins on the treadmill. Any idea the approximate calories burned?

Has little to do with strength training. But check out:

Why do you say this has little to do with strength training? It is a part of my training routine. I don't lift everyday. Somedays are only cardio. However, it does play into my training.
Thanks for the link.

You don't really build any muscles or strength with cardio. It is a far stretch, but some think they strengthen heart, I suppose.
Glad, I could help.

Not an accurate one.
The two things we do not know that would help a lot are what is your maximum heart rate, and what is your VO2max.

The heart frequently strengthens from cardio if you do it at an intense enough level. This effect is often called "athlete's heart".
http://www.hopkinsmedicine.org/cardiomyopathy/athlete's_heart.htm
from which:
"The specific nature of athletic training itself has a major influence on the type and magnitude of the changes in LV dimensions. For example, in a study of almost 1000 elite Italian athletes, only about 2% had an LV wall thickness of > 13 mm (in the gray zone between physiological hypertrophy and HCM), and this subset was confined to those in rowing sports and cycling. Conversely, most other forms of training, including isometric (or power) sports such as weight-lifting or wrestling, were not associated with absolute increases in wall thickness beyond 12 mm."
so yes, it's "cardio" exercise that causes the heart to hypertrophy.
Here is an article from the medical literature explaining this condition to doctors, so it's pretty detailed:
http://heart.bmjjournals.com/cgi/content/full/86/6/722
One thing that you get from this is that although the exercise causes this hypertrophy of the heart, it does not always cause it in all people that exercise - they think there are genetic and other factors. But if it does happen, they know it is due to exercise because when the exercise is discontinued (see the stuff about seasonal athletes) the changes reverse.
Establishing a cardio base is also considered important by some for strength training:
