Final answer:
To calculate % Max HR and HR target, subtract age from 220 for Max HR and multiply by the desired intensity percentage for the HR target.
Step-by-step explanation:
To calculate your % Maximum Heart Rate (% Max HR) and Heart Rate (HR) target, you can use the following formula: Max HR = 220 - Age; then to find your HR target, you multiply your Max HR by the desired percentage (e.g., 0.50-0.85 for moderate to vigorous exercise intensity). For example, if you are 40 years old, your Max HR would be 220 - 40 = 180 beats per minute (bpm). If your desired exercise intensity is 70%, you would calculate your target HR by multiplying the Max HR by 0.70, resulting in a target HR of 126 bpm.
