Fads are common in the fitness world, just think of Richard Simmons videos, Boflex infomercials and Shake Weights as examples. Some fitness fads, however, can stand the test of time.
Recently there has been increased popularity in strength training. This type of exercise, which is also referred to as resistance training, is designed to improve muscular fitness as the muscles generate force against external stimuli.1
Unlike other fitness fads, strength training is timeless because it helps to preserve and maintain healthy muscle.
