Those unfamiliar with mixed martial arts back when Dublin hosted UFC 93 back in 2009 will certainly be aware of the sport now.

The rise of the sport into the social conciousness has been fascinating and has been helped along by one of the Ultimate Fighting Championship's biggest stars, Conor McGregor.

McGregor is one of a number of fighter's who have trained at John Kavanagh's Straight Blast Gym and the growth in popularity has become subject of a news feature in for Channel 4.

Featuring in the video are fighters like Aisling Daly and Cian Cowley, who spoke to Newstalk.com in the documentary, I’ll Smile When I’m Rich: Inside Irish MMA.
