Natacha Oceane
British biophysicist, sprinter, and Iron Man Natacha Oceane uses her YouTube channel to share videos approved by a GB Olympic athlete. One of her most recent, a 20-minute no-equipment HIIT workout is also no-impact and makes no noise, making it ideal for those who are worried about disturbing the neighbors. All you need is the space of a mat, and Natacha has included clear, timed intervals to make it easy to follow at home.
