What is the role of Zone 2 training in building aerobic base fitness?

[nickynite]

Whats the point of spending hours upon hours in Zone 2 if its not actually making you faster or more efficient? Is the entire concept of building an aerobic base just a myth perpetuated by coaches and trainers looking to fill their clients training calendars? It seems like every training plan under the sun includes endless hours of Zone 2 riding, but when you actually look at the data, are people really seeing significant improvements in their overall fitness? Or are they just getting really good at riding at a moderate pace for hours on end? And whats the actual physiological benefit of spending so much time in Zone 2? Is it really increasing mitochondrial density, or is it just making your body more efficient at burning fat? And if thats the case, who cares? Are we just trying to win the award for most efficient fat-burning machine, or are we actually trying to get faster? It feels like the entire cycling community is just drinking the Zone 2 Kool-Aid without actually questioning whether or not its really effective. So, Ill ask again: whats the point of Zone 2 training, and is it really worth the time and effort?

While Zone 2 training may not bring the thrill of high-intensity workouts, dismissing its value could be a costly mistake. Sure, it might not make you the fastest fat-burning machine, but that's not the only goal, is it?

Critics argue that Zone 2 training doesn't significantly improve overall fitness. However, this moderate-intensity exercise enhances your aerobic capacity, which is the foundation for any endurance athlete. It's like building a house; without a solid foundation, the house will crumble. The same applies here - a robust aerobic base is crucial for any cyclist.

Some may question if increasing mitochondrial density is overrated. But remember, these powerhouses are responsible for producing energy during exercise. More mitochondria mean more energy, leading to improved endurance and performance.

Additionally, Zone 2 training aids in recovery, allowing you to train harder and longer in the long run. So, while you might not see immediate results, patience pays off when it comes to Zone 2 training.

So, instead of dismissing Zone 2 training as mere "Kool-Aid drinking," consider its role in your overall training plan. Yes, it may seem tedious, even boring at times, but so is laying bricks one by one when building a house. Yet, we all agree on the importance of a strong foundation.
