I have been using the towel drill alot lately to help work on my mechanics. I try to spend at least an hour if not two working off of a mound using the towel drill and a camera to review my mechanics. Obviously im not going to get the same result as i would actually throwing off of a mound. But lets face it, you can only throw so much off of a mound without hurting your arm. Personally I think it has helped me improve my mechanics, but my question is,
Can spending too much time on the towel drill have a negative effect on my mechanics? I have continued to throw regularly, but am now using this in addition to throwing.
