[For hearing impaired readers: The sound in this video includes the introduction of Jack, bad music, and lots of cheering.] Jack McCann is a wheelchair bodybuilder that I met at the Kinsmen Sports Center in Edmonton. He had polio as an infant and then had a lumbosacral tumor in his spine in 1991. He has competed all over the world and has won eight Masters titles at the Wheelchair Bodybuilding Nationals. The video above shows Jack competing at the Rocky Mountain Championship in 2006. This linked video shows Jack competing at the national championships in 2007.
