aerobic base

An aerobic base refers to your body's ability to efficiently use oxygen to produce energy during sustained, moderate-intensity exercise. Building a strong aerobic base improves endurance, allowing you to exercise longer with less fatigue. It involves developing your cardiovascular system, increasing the capacity of your heart, lungs, and blood vessels to deliver oxygen to your muscles, and enhancing your muscles’ ability to utilize that oxygen. Training at this level typically includes activities like steady-state running, cycling, or swimming. A solid aerobic base is foundational for more intense training and overall fitness, helping you perform better and recover faster.
