Heart rate zones are specific ranges of heartbeats per minute that correspond to different exercise intensities. Aerobic base building focuses on training within lower heart rate zones to enhance cardiovascular efficiency and endurance. By consistently exercising in these zones, the body improves its ability to use oxygen, burn fat for fuel, and delay fatigue. This foundational training is essential for athletes seeking long-term performance gains and overall cardiovascular health.

What are heart rate zones?
Heart rate zones are bands of exercise intensity shown as a percentage of your max heart rate (or heart rate reserve) to help pace workouts from easy to hard.
What is aerobic base building?
Aerobic base building means training mainly in the lower heart rate zones (roughly Zone 1–Zone 2) to boost cardiovascular efficiency and endurance for longer, steady efforts.
Why train in lower heart rate zones for endurance?
Lower-zone training strengthens the heart's efficiency, increases fat oxidation, and promotes more mitochondria and capillaries, leading to better endurance with less fatigue.
How do I determine my heart rate zones?
Estimate max HR as 220 minus age, then apply zone percentages (e.g., Zone 2 ~60–70% of max). For a personalized approach, use heart rate reserve: target = HRrest + % × (HRmax − HRrest).
