Yeah I started walking a lot since 2021 (before I walked but just a few km to/from work, and sometimes I'd take a bus), since 2020 I worked remotely and I realized how much I need these walks, started walking around 7km daily on average, with 20-30km walks on weekends.

It fixed my back pains. It made me lose weight. It gave me time to reflect on my long-avoided problems. Productivity is like the least important benefit.
