Let your older female clients know that the exercise they are doing with you today may give them many more tomorrows, according to a research report published in the Journal of the American Medical Association, May 14.
If (but, of course, not only if) you have a naturally aggressive client looking to lose weight or boost his fitness, you can address both issues simultaneously by having him don a pair of boxing gloves.
Pick up any packaged food, and you will see the number of calories listed on the label. Of course, nonpackaged foods, such as fresh produce, have calories, too; they just don’t carry labels telling you how many. Most people know that the body uses the calories contained in foods for energy and that, if they consume more calories than they expend, they will gain weight. (They also know that, if they do the opposite, they will lose weight.) Nonetheless, what exactly is a calorie, why do foods have calories and how does the body use them?
Because load theoretically increases as mechanical advantage increases, the addition of chains or elastic bands to conventional barbell squats had been thought to boost the loading during the ascent phase, but no research had confirmed this notion.

Typically, after age 30, the brain’s gray matter (the thin layers of cell bodies such as neurons and support cells involved in learning and memory) and white matter (the myelin sheath containing the nerve fibers that transmit signals throughout the brain) shrink in a manner analogous to a person’s cognitive decline. However, a study published in the February 2003 issue of the Journals of Gerontology Series
A: Biological Sciences and Medical Sciences was the first
to show that physical fitness may deter an older person’s loss of these vital brain tissues.
