Cardiovascular training can elicit positive benefits by increasing caloric expenditure, improving VO2max, increasing fat oxidation (depending on intensity and duration), and decreasing body mass (via increasing daily caloric expenditure), amongst other things. However, we must take into account that most gym endurance training equipment (e.g., treadmill, elliptical) and wearable calorie counters have shown inaccurate results in regard to estimating total caloric expenditure.
