Query: You'll Sweat but I couldn't get past the Terrible Form

First of all if you're looking for something short, this is not it. The workout is 89 minutes. I needed something I could work out to 30-40 mins a few times a week. But the thing that bothered me the most about this workout was that Ms. Bento has terrible form. If she ever actually punched someone with those punches she would hurt herself. I have a black belt in martial arts and ten years of training and I could not get past how bad her form was--I would be afraid that viewers would inadvertently hurt themselves imitating her. She has clearly not had any formal training at all in throwing kicks or punches. It is extremely disturbing. I definitely got a good sweat on but could not get past her terrible form. I had to modify almost everything so that I didn't injure myself by following her poor form.
