<human>: Which are better: a treadmill or elliptical?
<bot>: It depends on what you're looking for. A treadmill is good if you want to run, walk, jog, or do other types of cardio exercises. An elliptical is more focused on strength training and aerobic exercise. If you're looking for something that combines both types of exercise, an Elliptical Cross-Trainer might be the best option.
