"...Before I put the NGR shoes on, I figured I’d walk for 10 minutes and get my try-the-shoes obligation over with, but I ended up enjoying a good 45-minute, brisk walking workout. I loved the slight-muscle-burn feeling that I’ve never felt while walking in normal shoes.
Found these No Gym Required type exercises provided by More magazine where the model is wearing NGR Shoes! That means she's getting a little more out of her workout by increasing the resistance in her legs and core!
The last exercise (Pilates Obliques) is really maximizing the usefulness of NGRs!
