The potential for asensei to provide quality feedback before bad habits are formed is really exciting", Helen Glover, 2x Olympic Gold Medallist and World #1 Rower. "Just when you thought (sports) technology couldn't get any cooler, along comes asensei", CBS Television "... the next frontier in the fitness tech revolution ... a wildly ambitious goal ... able to guide you through everything from form and recovery to metrics and goals while improving your individual results ... future of personal training", Men's Health Here's what users had to say: "someone keeping an eye on you the whole time is really cool because ... it keeps you honest, keeps you on track in a way that I don't think a coach normally can unless you are doing a one on one session, so it was the benefit of a one on one, with the class dynamic, which I really like!" "It's a cool product. I've never ever seen anything like that. In 5 minutes I learned how to row, I thought I was doing it right, but I wasn't" "(asensei) said don't worry there's a bunch of exercises I'm going to give to you afterwards that are going to help you on that. ... that's amazing. ... this is not just about now, it's like building a relationship."
