By performing an additional set (50% to 100% more sets) only 0 to 5% more progress will be observed. Each additional set yields even less progress to a point of diminishing return. The time saved with an abbreviated weight training program can often be used more wisely elsewhere in a program. More aerobics should be performed if fat loss, toning, or cardiovascular conditioning is a goal. Duration is a more important component with aerobics exercise. Alternatively, more sports-specific training can be performed if improvement of athletic ability is a goal. In addition, more rest can be take between sets if strength is a goal. Finally, more time can be spent recuperating after workouts, decreasing the stagnant or injurious effects of overtraining.
