To add aerobic exercise to her workout routine, Camille should consider jumping rope.
Jumping rope is an excellent form of aerobic exercise that increases heart rate and endurance. While kickboxing can also provide a good cardiovascular workout, jumping rope is more straightforwardly recognized as an aerobic exercise. Weightlifting and sprinting, on the other hand, are not primarily aerobic; weightlifting focuses on strength training, and sprinting is usually considered anaerobic due to its high intensity over a short duration.
