Answer to Question 1
Multiple- and single-joint exercises are used in strength training.
Multiple-joint exercises, such as the squat, bench press, and lat pull-down, require more skill and complex neural responses than single-joint exercises. Multiple-joint exercises also allow you to lift more weight and develop more strength.
Single-joint exercises, such as the arm curl or knee extension, are used to target specific muscles for further development.
Both are recommended for a comprehensive training program.
Answer to Question 2
Because muscular strength and endurance are important in developing and maintaining overall fitness and well-being, the principles necessary to develop a strength-training program have to be understood, just as in the prescription for cardiorespiratory endurance. These principles are mode, resistance, sets, frequency, and volume of training. The key factor in successful muscular strength development is the individualization of the program according to these principles and the person's goals, as well as the magnitude of the individual's effort during training itself.
