Hi, I am new to this forum and this is my first post. I took karate a couple years ago in college, and in one of the training sessions, our instructor had us lie down and he walked on our stomachs. Has anyone else experienced this type of training in their martial arts class? If so, do you know what purpose it serves? I thought it was to condition our stomachs and truly I don't think it is a bad exercise if the instructor is careful. One thing I will mention is that it seems like female instructors would be more effective in this type of training because they tend to be lighter and are less likely to cause injury. Any insight is appreciated. Thanks.
