I did this workout last week and I can see the many benefits from this given I train consistently with it.  It will improve areas like cardio, endurance, power, combinations, coordination, and many more. 
Start out by doing a good warm up and stretching before you do this.  I jump roped for about a minute and a half, and then did some stretching, before starting this to make sure I did this workout efficiently.
