I found Jennifer Aniston’s workout at Self Magazine’s website. It’s perfect to do at home and without any equipment. The cardio portion you could even modify by doing sprint intervals at a local high school track instead of on an elliptical machine.
I’ve tried it a few times and was dripping sweat by the end of it. At the very least, it’s a few new moves to incorporate into your regular workout when you need to switch it up to keep seeing results.
