To estimate your heart rate during exercise like jumping jacks, you can use the formula you provided, which is based on the maximum heart rate (MHR) method.
First, calculate your maximum heart rate (MHR):
- MHR = 220 - age
- For you: MHR = 220 - 17 = 203 beats per minute (bpm).
Next, calculate the target heart rate zone, which suggests a range of 50% to 85% of your MHR:
- Lower end (50%): 203 bpm × 0.50 = 101.5 bpm
- Upper end (85%): 203 bpm × 0.85 = 172.55 bpm
Therefore, during jumping jacks, your target heart rate zone would be approximately:
- 101.5 bpm to 172.55 bpm
While the actual heart rate during your workout can vary depending on your fitness level and intensity of the exercise, you can aim to keep your heart rate within this range for a cardiovascular workout.
