I hate to say it, but I've been letting myself go in recent years. I used to hit the gym regularly and was always in great shape until a few years ago. Then work, kids, and the day-to-day grind pretty much took over my life. Before I knew it, I had packed on an extra 15 pounds. To make matters worse, I had no energy or motivation to drag myself to the gym anymore. Still, I had to do something, so I started by checking into the whole "shape-up shoes" trend that began with Masai Barefoot Technology. In case you don't know, Masai Barefoot Technology pioneered the whole rocker bottom shoe movement way back in 1990. This type of shoe has very thick soles and a rounded heel, making them rather unstable -- which is the point. Because of the inherent instability of this footwear, you're forced to constantly use your muscles to balance yourself properly. This is supposed to help people burn extra calories without overexerting themselves. MBT shoes by Masai Barefoot Tech...
