Cardio age improvement

[M, early 30’s] Not sure what caused it. I’m in an extremely hot climate and hike 3-4x a week (4k total steps) w/ 10 lbs of water. I’ve ramped up this trend over the last 3 weeks. HR and HRV are all the same (44-48 sleeping, 120-150 HRV). Let’s see if this continues.

Anyone else improve or get worse?
