Fat blastin' cardio - all focused on the core! What could be better than that?
NOTE: Be sure to start with a warm-up, and end with a cool-down stretch.
SuperSet (alternate) 2 exercises for 2 sets.
Set ONE = 45 secs work: 45 secs rest | Set TWO = 30 secs work: 15 secs rest.
Then move to the next 2 exercises.
