In the past decade, weight and other forms of strength training have become an important part of women’s exercise programs. If you are interested in working with the ever-growing Baby Boomer market, weight training is considered to be the best workout for that age group. For those who want to specialize in strength training, a certification with the National Strength and Conditioning Association (NSCA) is the way to go. This is the organization that will teach you everything you need to know about weight training machines, free weights, muscular sequences, choosing the right fitness training schedule, etc. In addition to the exams, NSCA offers a variety of online fitness training manuals.
