Anyone feel in terms of results the gym is overrated?

The fact that walking is low intensity, low stress is one of the reasons it is potential useful to someone who lifts or does other more high intensity training if they want to burn a few more calories without risking over training or more impact on joints. Or they might want to just do something active without compromising the rest of their training. The inoffensive nature of walking is kind of its niche.

Depending on how briskly you walk and whether it's on a incline is going to dictate whether it's a negligible amount of calories burned or something more substantial, but if you're walking several times a week it adds up. It's not uncommon for people with physique goals to throw in morning walks while fasted.

Benefits like stress relief have a subject element but the restorative benefit of increased blood flow is real.

Stuart McGill also has cited research that some low back pain sufferers can obtain relief from brisk walking. I don't have it in front of me but the swinging arm movement seems to be part of why.

As for the name of the forum... Fitness isn't always about death or glory training, sometimes it's a lot more modest, because some people need to start somewhere and it might be at the very bottom. Sometimes fitness is about small improvements or little habits that, over time, amount to something more significant, and are the way markers in people's journeys from sedentary to fit.
