During cardio workouts, which of the following is a recommended practice to prevent dizziness?

Staying hydrated before and during exercise is crucial for preventing dizziness, particularly during cardio workouts. Hydration helps maintain blood volume, regulates body temperature, and supports overall cardiovascular function. When the body is dehydrated, it can lead to a drop in blood pressure and reduced blood flow to the brain, which may result in dizziness or lightheadedness during physical activity. Therefore, ensuring adequate fluid intake not only helps to sustain energy levels but also minimizes the risk of experiencing dizziness while exercising.

Other options, while they may seem relevant in some contexts, do not effectively address the issue of dizziness in the same way proper hydration does. Ending a workout abruptly may actually lead to a sudden change in blood flow and contribute to dizziness rather than preventing it. Decreasing the duration of cardio sessions might not be necessary if hydration practices are followed, and only performing low-intensity exercises could limit the benefits of cardio training and may not be feasible for everyone. Thus, maintaining hydration stands out as the most effective strategy for preventing dizziness during cardio workouts.
