I find it interesting that the article is about exercise and the title picture is yoga. In fact near the top

> To a best approximation, aerobic fitness and weight-training seem to increase our metabolism, improve mitochondrial function, fortify our immune system, reduce inflammation, improve tissue-specific adaptations, and protect against disease.

Yoga is neither aerobic fitness nor weight training

note: I do yoga probably about twice a month (should do more) so I'm not dissing yoga. I'm only noting that the picture of yoga seems to have nothing to do with the article.
