Final answer:
No, it is not sufficient to do just one set of each exercise for a strength training program to develop general fitness.
Step-by-step explanation:
No, it is not sufficient to do just one set of each exercise for a strength training program to develop general fitness. For effective strength training, the intensity of the exercise must continually be increased. This means gradually increasing the weight or resistance used in each exercise to challenge the muscles and promote muscle growth. Doing just one set may not provide enough stimulus for muscle growth and may limit the overall benefits of the training program.
