For me with this experience, the biggest change should be the change of body posture. I used to bend over when I walked, but now I will straighten my back unconsciously wherever I go.

I don't always walk with my head down as before. I am very satisfied with this change. Every time I see the envious eyes of others, I am extremely proud. Fitness can not only improve my health, but also be particularly beneficial to my physical and mental health, so everyone must actively participate.
