99% of the time I'm doing cardio for conditioning, thereby I don't really like walks. Fat loss is always taken care of in the kitchen for me.
I don't have problem with light walks or incline walks, they're refreshing, and yes, it can help recovery if it isn't excess.
Walking is proven to be extremely effective for those who know how to eat while on diet. Most of the BB-ers got stage-cut with proper diet and steady state walks for cardio.
But! Those who eat pizza-chocolate-ice cream and all type of shit, drink their coffee with 20grams of sugar and cream, powder, drink their share of soda and juice while sitting at a desk and on the couch 12hours a day...
Well, these fucked up folk usually think that hopping on the treadmill for 2.5 kph walks for 20 minute a day will help them to loose fat.. Everyone knows their results: "ahh, I go to the gym, but it aint worth nothing.. I quit!"
So walking is GREAT if the other parameters of the equation are in the right place with the right values.
