Whats the obsession with zone 2 training when its clear that no ones actually addressing the elephant in the room - sleep quality? Every single study on the topic shows that subpar sleep is a major performance killer, but do we ever see coaches or training plans emphasize the importance of a good nights rest? Nope, its all about slogging away for hours in zone 2, completely ignoring the fact that youre probably running on fumes.
Meanwhile, the science is clear: poor sleep quality is linked to decreased aerobic capacity, reduced lactate threshold, and impaired glucose metabolism - all of which are critical for zone 2 performance. And lets not forget about the impact of sleep deprivation on inflammation, oxidative stress, and immune function, all of which can have a devastating impact on your ability to recover from hard training.
So, Ill ask the question: how many of you are actually prioritizing sleep as part of your training plan? Or are you just winging it, hoping that a few extra hours in zone 2 will magically compensate for your chronic sleep deprivation? Newsflash: it wont. In fact, the more you neglect your sleep, the more youre likely to plateau or even regress in your training.
And another thing - whats with the assumption that zone 2 is even the most effective way to train? Has anyone stopped to consider that maybe, just maybe, were all being sold a bill of goods by the coaching and training industry? That maybe there are better, more efficient ways to train that dont involve sacrificing your sleep and overall health? Im not holding my breath for a thoughtful response, but Im curious to see how many of you will actually address the issue at hand.
