Former Bombers fitness advisor Stu Cormack says all clear on his watch at Windy Hill Former Essendon high performance coach Stuart Cormack. THE man who preceded Dean Robinson as Essendon high performance manager says nothing unethical happened on his watch at Windy Hill. Stuart Cormack, who left at the end of the 2011 season, told the Herald Sun yesterday his sports science and fitness staff did not engage in irregular practices. "No, not by any of the people I closely worked with," Cormack said. But I couldn't speak if things were being discussed outside the group I worked with. I'd have no knowledge of that. There certainly weren't any instructions to do anything untoward. Cormack, a senior lecturer in sports science at the Australian Catholic University, said the club had a supplements program headed by a full-time performance dietitian. "Supplements are part of the brief of someone in that (sports science) role," he said. But there's a well-documented categorisation for supplements which appears on the AIS (Australian Institute of Sport) website. There were certainly, at that time, only things appropriately categorised under that scheme (used in Essendon's program). Cormack's relationship with Essendon had a strained ending. He appeared on the ABC's Four Corners program last night and said: "That organisation had a view on the path they wanted to take, they didn't believe I was the person for that role and they're entitled to do that." On Essendon's conditioning philosophy, he said: "There was certainly a desire to . . . get the athletes bigger and stronger fairly quickly, but you know there was never a suggestion . . . from anyone that that would involve . . . practices that I wasn't comfortable with from a . . . legal perspective, just from a training design and implementation perspective." Cormack's program centred on weights and by the end the club was keen on a running-based program. He told the Herald Sun: "The coaching group decided they knew more about the way a training program should be designed than me, and therefore I wasn't the person for the role."
