I'm sure many of you have seen this and thought everything from "It's just gimmicky..." to "That looks awesome!" then looked at the price (around $130-150) and said "I can live without it." Well I picked one up and can say I'm very pleased with it and the 12 lbs model is aptly named for the burn you will get when using it. You can structure entire workouts around it or you can use it to shake up your normal routine. It is a stellar piece of equipment if you travel a lot - this would be great for you, Kevin. Anyone using it for a couple of weeks will then probably think it was money well spent, I know I do.
