Query: this one's tough!

This is a tough video. I consider myself an intermediate to intermediate/advanced exerciser and I do this video for a tougher workout. There are modifications (easy and moderate)if needed. The workout is designed as circuts. The cardio includes lots of pliometrics, jumping rope, burpees, lunges, etc. These alternate with bried toning sections using weights for upper body toning.
