Background

Slack describes himself as “a martial arts fanatic from the U.K. who got involved in karate very young, then boxing, then most recently jiu-jitsu". Initially he started researching and writing for his own training improvement in order to compensate for his "shortcomings in his own physicality", and later, by motivation to showcase to the casual fan and the mainstream media how MMA is a highly skillful art form.
Slack's pen name is a reference to Jack Slack the "Norfolk Butcher", the 1743 Norfolk boxing champion who defeated famed English boxing champion Jack Broughton in 1750 as a heavy underdog and remained undefeated as champion until 1760. Slack has said that he does not particularly admire the man, whose life was "more than a little shady", but that the name has "a ring to it".

Writing

Slack's first public contribution to analysing striking came in the form of sharing passages from published authors from his book collection. The first one posted on MMASHARE forum August 2011 titled Jimmy Wilde - The Art of Boxing. From January 2012 onwards he started to write and publish his analytical breakdown on his newly opened blog FightsGoneBy, while promoting his articles on major MMA forums and gaining popularity.

The editor of Fightland contacted Slack and offered him a position as a writer.

Though a regular writer, Slack was not exclusive to Fightland, and wrote articles for Fighters Only magazine and Unibet UK blog. Slack is known for his use of animated GIFs in his articles.
