Weight training has a positive effect on a person's mental well being. Initially the primary focus of a child's program should be on developing proper technique, and learning the exercises. Adolescents should focus on a program that involves 8-10 exercises concentrating on the major muscle groups. This type of program will provide a solid foundation to build on before increasing frequency, intensity, and duration of the workout. Finally the amount of rest between workouts is as important as the amount of time spent in the gym.
Rest is needed to replace the energy stores in the muscles after a workout.
Always take time between exercise sets to rest and allow a day of rest between training sessions. In order to maintain flexibility, exercises should be performed through the full range of motion. Weight training actually improves flexibility by lengthening the muscle's functional range. Contrary to popular belief, weight training does not make you inflexible. If the adolescent has a history of high blood pressure, a heart ailment, or suffer from any major illness consult your physician before starting any exercise program.
