Explanation:

• Option A: Over - exerting the heart during exercise is not advisable as it can lead to health risks, so this statement is false.
• Option B: The formula to calculate maximum heart rate is indeed \(220 - \text{age}\), so this statement is true.
• Option C: The recommended exercise heart rate is usually in the range of 50 - 85% of the maximum heart rate (not 30%), so this statement is false.
• Option D: Since A and C are false, this option is also false.

Answer:

B. Maximum heart rate can be calculated by taking 220 minus your age.
