FAN FAVORITE: The Physics of Resistance Exercise with Doug Brignole and Ron Penna

Every year, countless individuals engage in a resistance training program in an attempt to either enlarge their muscle size for enhanced physical appearance, increase their muscle strength for improved athletic performance, or maintain the ability to perform the activities of daily living that are important to them. Most of these fitness enthusiasts perform standard resistance exercises, as recommended by fitness professionals, personal trainers, and friends, or as presented in books, magazines, and websites. These standard resistance exercises are generally effective for the first few months of training, during which time most new participants experience gains in both muscle size and strength. Sooner or later, however, they encounter either an exercise-related injury or a muscle-development plateau.
