Does the above chart have any significance regarding losing weight and exercising?
Sure. It's basically a somatotype chart. Refer to my answer above to KiddingMe.
I have always heard about pear shape vs. apple shape.
I'm definitely an apple.
More like the athletic build on this chart, except I'm not athletic.
I don't have a waist and I never had much of a waist even when I was thin.
So, I'm more testosterone influenced according to this chart?
Testosterone has nothing to do with your skeletal structure as far as somatotype per say. Where testosterone affects the skeleton are when you reach puberty and begin to increase the production of sex hormones and again later in life when your sex hormones decrease. Once sex hormones reach "adult" level, the signal to the bone growth process is "stop growing, you're an adult now." The bones growth plates seal and the bones cease to grow in length. But the size and density of bones don't affect sex hormone levels, rather it's the other way round. You can be an endomorph and have a high free testosterone count and have a Mesomorph structure with a low count. Healthy levels of sex hormones result in strong bones, low level else have the opposite effect. Hence the effects of low estrogen levels can be seen in post menopausal women who are prone to loss of bone density (osteoporosis). Testosterone is a primary component for building muscle however, and people who have higher levels, regardless of somatotype are prone to building bigger, stronger muscles than those with lower levels of testosterone.
What does that mean regarding working out?
As explained, skeletal structure does not dictate how much free testosterone you have available. But if you had higher than normal levels, you would get bigger stronger muscles and burn fat faster.
