Feedback please.

Would love to hear your thoughts on my submissions. Thanks.

Most of the designs were quite similar with either replacing an A, or K or I with a person running or walking. So I eliminated all the ones that looked like runners or strollers and only kept the ones that were actual power walkers. I also eliminated any that were just the name and nothing else.
The one I am leaning toward at walking feet in a heart with an ecg graph. This one represents hart health through walking.

I hope that is helpful

Thank you
