Question 1

What is target heart rate?

Accepted Answer

Target heart rate is the range of heartbeats per minute during exercise that ensures you're training at the right intensity.

Question 2

How is max heart rate calculated?

Accepted Answer

The most common formula is: Max HR = 220 – age. More accurate formulas exist for different populations.

Question 3

What are heart rate zones?

Accepted Answer

Zone 1 (50–60% max): Warm up. Zone 2 (60–70%): Fat burning. Zone 3 (70–80%): Aerobic. Zone 4 (80–90%): Threshold. Zone 5 (90–100%): Maximum.

Question 4

What is the fat burning zone?

Accepted Answer

The fat burning zone is 60–70% of max heart rate. While fat is the primary fuel, higher intensities burn more total calories.

Question 5

What is the Karvonen formula?

Accepted Answer

Target HR = ((Max HR – Resting HR) × % Intensity) + Resting HR. It personalizes zones using your resting heart rate.
