What is the primary method to calculate your aerobic threshold?

• By measuring your maximum heart rate

• By determining the heart rate at which lactate begins to accumulate in the blood

• By calculating your VO2 max

• By assessing your resting heart rate

Which of the following activities is most effective for enhancing aerobic capacity?

• Sprinting

• Weightlifting

• Long-distance cycling

• High-intensity interval training (HIIT)

How can you calculate your anaerobic threshold?

• By measuring the point at which your breathing becomes laboured

• By determining the heart rate at which you can no longer sustain exercise

• By calculating your VO2 max

• By assessing your resting heart rate

Which activity is best suited to improve anaerobic capacity?

• Marathon running

• Yoga
