Question

how does real-time data from fitness technology assist individuals during exercise?
it predicts future performance based on past workouts.
it replaces the need for any professional training advice.
it adjusts the workout routine and requires no input from the individual.
it allows for immediate adjustments to ensure workouts are effective and safe.

Explanation:

• Analyze each option:
• Option 1: Predicting future performance is more about historical analysis, not real - time assistance during exercise.
• Option 2: Fitness technology can't replace professional training advice as professionals have in - depth knowledge beyond just data.
• Option 3: Fitness technology usually needs some input or feedback from the individual, it can't fully adjust without any input.
• Option 4: Real - time data from fitness tech (like heart rate, calories burned etc.) allows people to make immediate adjustments during exercise to make sure the workout is effective (e.g., increasing intensity if heart rate is too low) and safe (e.g., decreasing intensity if heart rate is too high).

Answer:

D. It allows for immediate adjustments to ensure workouts are effective and safe.
