It’s always good to expand your vocabulary of exercises, and these ones target two of the most common areas that people want to improve – at the same time. There are six exercises as promised which will tune your abs as well as your glutes. What I like is the presentation – each exercise has a mini – video, maybe 5 seconds, on loop where a pretty woman demonstrates the technique and then a short bullet point text to give you the essentials in print. Very well done – clear and to the point. Enjoy!
