• Using a thermometer

Answer explanation

Heart rate can be measured without using a monitor by taking the pulse manually. This involves feeling the pulse at certain points on the body, such as the wrist or neck, and counting the number of beats per minute.

What is the relationship between exercise intensity and heart rate?

• The heart rate remains constant regardless of the intensity of the exercise.

• The heart rate increases with the intensity of the exercise.

• The heart rate decreases with the intensity of the exercise.

• There is no relationship between the intensity of the exercise and the heart rate.

Answer explanation

The heart rate increases with exercise intensity.

What type of exercise can help maintain a healthy heart rate?

• Weightlifting exercise

• Yoga

• High-intensity exercise
