A pedometer helps in achieving fitness goals by counting steps during a workout, motivating individuals to increase their activity level and consequently burn more calories.
Step-by-step explanation:
A pedometer helps people reach their fitness goals by counting the number of steps they take during a workout, which is answer C to the question posed. By tracking steps, pedometers encourage individuals to be more active and can provide motivation to achieve a daily step goal, commonly recommended to be about 10,000 steps. This can contribute to increasing the overall physical activity level of the person, which is essential for burning calories and maintaining a balance between calories consumed and expended. Engaging in physical activity can also raise one's basal metabolic rate (BMR), leading to greater energy consumption even at rest.
