40 jumping jack
Please describe a starting heart rate and an ending heart rate!
The starting heart rate before performing 40 jumping jacks will vary from person to person based on their individual fitness level, age, and overall cardiovascular health. On average, a resting heart rate for adults is approximately 60-100 beats per minute.
After completing 40 jumping jacks, the heart rate will generally increase due to the increase in physical activity and demand on the cardiovascular system. The ending heart rate will largely depend on factors such as the intensity exerted during the exercise, the individual's fitness level, and their body's response to the activity. It is normal for the heart rate to significantly increase during exercise, and it may reach levels of 120-180 beats per minute or even higher for certain individuals.
Keep in mind that heart rate recovery, which refers to the rate at which the heart returns to its resting state after exercise, is also important. In a generally healthy individual, the heart rate should gradually decline back to the resting heart rate within a few minutes after stopping the activity.
It is worth mentioning that heart rate responses during exercise can differ from person to person, so it is always recommended to consult with a healthcare professional for personalized advice regarding your individual fitness goals and heart health.
