If you are the happy owner of a jump rope and a floor the Power Line will help you whip up a healthy sheen of sweat in no time at all. The workout is light and it's fast and it works pretty much all the major muscle groups and places a pretty decent load on your VO2 Max which means the more frequently you do it, the more benefit you'll get out of it. And since it's only Level II in terms of difficulty EC is practically a must.
Extra Credit: 1 minute rest between sets.
