When you start walking after a long while, it's the strangest experience ever

The day before yesterday I didn't go to the yoga class, and walked for 2 hours at the part instead. Earlier in the week, I went to volunteer-interlaken parks.

I'm beginning to realize perhaps walking is indeed a more challenging and interesting activity than I had given it credit for. Because without the habit of regular walks, I get tired every 40 minutes or so, need rests, can feel the walk on my calves and certain muscles, and sore way earlier than I used to. My walking stamina has reduced. I'm building muscles and everything with yoga, yes, but these are different skillsets and workouts.

So walking intensely after some time was the strangest experience ever, because it felt like I was doing something new, something actually tiring, a proper 'workout'. What I'm thinking then is this: in the future, I'll keep yoga as a part of my rotation, but it cannot replace my personal workout such as pushups and situps etcetera, and the walks are unique in their own way. If I want to do PCT in the foreseeable future, I need to be walking 10k steps every day, no matter how many hours of yoga I'm doing....
