The Importance of Building an Aerobic Foundation for High End Aerobic Development

Easy running and time on your feet will cause your muscles to adapt and increase mitochondrial content. Intense interval work complements this foundation by increasing content through high intensity training. Moving from an aerobic foundation to high end aerobic development requires a shift to a double threshold approach. This pushes the limits of your aerobic ability and develops your threshold. The goal is to have a high level of mitochondria and improved aerobic capacity.
