We need to hear less about minimum exercise requirements and more about how more exercise is better. Every wonder why aerobic capacity seems to be not transferable from one sport to another. People need to consider the range. It's really a misconception, but non-transferable capacity is consistent with most people's experience. Why? I know of no theory that could possibly explain why capacity doesn't transfer between sports. Now you have probably surmised that I have discovered the answer to this conundrum. I think I have the reason. Advanced aerobic training is required to create a capacity that is transferable to other sports. This is observable in the triathletes. The failure to realize this resides in the common misconception that there is a minimum amount of necessary exercise. This is false. As a result of this misconception, people's musculature is under-developed, and they falsely perceive that aerobic capacity isn't transferred. More exercise is almost always better.
