Marcos René Maidana is an Argentine former professional boxer who competed from 2004 to 2014. He held world championships in two weight classes, including the WBA (Regular) super lightweight title from 2011 to 2012, and the WBA welterweight title from 2013 to 2014. A versatile brawler in the ring, Maidana was well known for his formidable punching power, and was never stopped in any of his five losses.

Throughout the history of gloved boxing styles, techniques and strategies have changed to varying degrees. Ring conditions, promoter demands, teaching techniques, and the influence of successful boxers are some of the reasons styles and strategies have fluctuated.
