Question

to set your intensity level, you need to __________. a. use your maximum heart rate, which is determined by subtracting age from 220 b. exercise for a minimum of 60 minutes each session c. increase your resting heart rate by increasing the weights you lift each week d. determine what it is by subtracting your age from 2,000 calories please select the best answer from the choices provided. o a o b o c o d

Explanation:

• Option A: The formula to calculate maximum heart rate is \( \text{Maximum Heart Rate}=220 - \text{Age}\). This maximum heart rate is used to set intensity levels (e.g., target heart - rate zones for different exercise intensities like moderate or vigorous).
• Option B: Exercising for a minimum of 60 minutes per session is more about the duration of exercise rather than setting the intensity level.
• Option C: Resting heart rate is not increased by increasing weights lifted each week in a way that directly sets intensity level. Also, increasing weights is more related to strength - training progression.
• Option D: Subtracting age from 2000 calories is not a valid method for determining exercise intensity. Calories are related to energy expenditure, not intensity level determination based on a physiological formula like heart rate.

Answer:

A. use your maximum heart rate, which is determined by subtracting age from 220
