The least helpful purchase for Herbert to make in an effort to reach his cardio endurance levels goal would be C. A nautilus machine. Nautilus machines are primarily designed for strength training and resistance workouts, rather than cardiovascular endurance. In contrast, the treadmill, bike, and elliptical machine are all equipment specifically geared toward improving cardiovascular fitness.
