Question

walking is a indoor activity?​

Answer 1

I guess no it’s an outdoor activity

Answer 2

Answer:

Unless you have a treadmill, going for a walk inside sounds like doing laps around your dinning table. ... "Walking is a fantastic cardio workout that is low-impact, while at the same time, can be a heart-racing, high-intensity exercise when done properly," says Aaptiv master trainer John Thornhill.
