i just started this week. I don't need to lose weight, but it's a good cardio workout during the winter months.
If you do it right, you're suppose to keep a tight core, and every jump move you make, you're suppose to pick up your knees, so it a good lower body workout. It achieves the same results as doing sprints.
Since i don't have to lose weight, I'll do this every 2 days and lift in the middle.
