And I think that's such a vague, big topic, but I'll let you kick off with your initial thoughts and then I'll add on from there.

AJ GolikGUEST
I unfortunately think the term zone two has been... taken by social media thrown into a blender and spit back out in a completely different context than it actually needs to be and similarly to double threshold training zone 2 training is applicable to some and not to all so by definition zone 2 training is any training that falls under your LT1 or your VT1 heart rate so Very easy aerobic.

AJ GolikGUEST
With that in mind, zone two training can benefit everybody, mainly athletes on the endurance side of things and on the like longer distance and longer duration side of things.

AJ GolikGUEST
But it also comes at a certain level of training and a certain volume of weekly training to really be needing to needing to do zone two training.

AJ GolikGUEST
And I put needing in quotes there because you have to earn the right to be able to train in zone two by building up your aerobic base to a point that that zone two training can then benefit you.

AJ GolikGUEST
And for the majority of the athletes that are listening, And for the majority of the people that are going to be going to Deco Worlds, this is not our full-time career.
