ABS workout, CORE workout at home in 2020 with Maria Khoreva ( Mariinsky ballet)

Heres a quick but quite a burning 15minute ab routine Its in 45 seconds on, 15 seconds rest format and it has 3 intervals of plank my favourite core exercise. We are not going to work on the ab muscles alone, there are a few exercises on back muscles and obliques, we shouldnt forget them. I love finishing my morning ballet training session with this workout, I feel like it burns the remaining calories. So I hope you guys like this video and also I would love if you leave your video suggestions in
