I could not write a better plug for an article than the excerpt of the following piece from the Boston Globe in regard to weight training, so read on and then follow the link to the whole article.
“The evidence in favor of strength training – at any age – “is nothing short of astonishing,’’ says William J. Evans, an exercise physiologist at the University of Arkansas for Medical Sciences. And it is “remarkably safe. There are no reports that I have seen to indicate that there are any safety issues. . . . Resistance exercise is actually safer than regular aerobic exercise as far as risks of a cardiac event.’’
“Leaders are visionaries with a poorly developed sense of fear and no concept of the odds against them. They make the impossible happen.”
