Jock Campbell told Brett Lee he had never got through a full first class season without getting injured, and then put a conditioning program in place that helped reshape one of the most injury-plagued careers in Australian cricket.
“I said to Brett, look, you’ve never got through a full first class season without getting injured. And we put a bunch of things in place then. And then he was just fantastic. He said yep, whatever you think. And he just jumped right on board.”

Campbell was Australia’s Head Strength and Conditioning Coach from November 2000 to November 2005. He joined at a time when Lee had already suffered a stress fracture in his lower back and an elbow stress fracture that kept him out of cricket for close to a year. Lee had taken 42 wickets at 16.07 in his first seven Tests. His body was already breaking down.
During Campbell’s five years with the team, Australia was ranked No.1 in both Test and ODI cricket, won the 2003 World Cup, and received the Laureus World Sports Award as the best team in any sport globally. The 2004/05 season produced the lowest percentage of player injuries in Australia’s recorded history. Campbell conditioned Glenn McGrath, Brett Lee, Jason Gillespie, and later worked closely with Mitchell Johnson.
Insider Read:
Lee had 15 times his body weight going through his front foot every single delivery. McGrath, bowling 15kph slower, still had 12 times. That gap between 12 and 15 is where careers end. Six ankle operations, two back stress fractures, one elbow reconstruction. That is what 150kph does to a human body without the right conditioning underneath it. Campbell saw that Lee’s problem was not one weak body part. It was the pattern. Long off-seasons, then sudden spikes in bowling load when the season started. That cycle breaks fast bowlers, not the pace.
Brett Lee has 15 times his body weight going through his front foot in his delivery stride, which imparts incredible stress on his ankle (six operations), knees and back (two stress fractures).

What Campbell Put in Place and How Lee Responded
The program went beyond physical conditioning. Campbell noted that Lee changed his diet and stopped drinking alcohol during the 2001-02 season as part of the overall plan. Campbell later wrote that studies showed athletes who drink are significantly more likely to suffer injury compared to those who do not, and that Lee followed this successfully.
Lee’s response to Campbell’s intervention defined the outcome. When told his body had never survived a full first class season, Lee did not push back. He did not negotiate. He said “yep, whatever you think” and committed fully. Campbell has described that willingness as “fantastic,” and it stands in contrast to the resistance that conditioning coaches often face from established international players.
The results showed in Lee’s career from that point forward. After returning from his elbow injury in 2001, Lee took 14 wickets at 25.14 against New Zealand that home summer. He was a central figure in Australia’s 2003 World Cup triumph, finishing as one of the tournament’s leading wicket takers and recording 160.1kph against Sri Lanka in the semi-final.
Lee’s career had two distinct phases. The first, before Campbell’s intervention, saw brilliant but interrupted bursts. 42 wickets in 7 Tests, then months on the sideline. The second phase, built on the conditioning structure Campbell designed, produced sustained output. After the 2005 Ashes, where Lee took 20 wickets in his comeback series, he claimed 48 wickets in 9 Tests at an average of 23.54 with three five-wicket hauls across six months against the West Indies and South Africa.
When McGrath retired after the 2006-07 Ashes, Lee stepped into the role of leading the attack. In the 2007-08 home season against Sri Lanka and India, he took 40 wickets at 20.58 and won the Allan Border Medal. That sustained performance at the highest pace in world cricket would not have been possible without the conditioning foundation laid years earlier.
Lee’s body did eventually give way. A foot stress fracture at the MCG in the 2008 Boxing Day Test against South Africa, followed by a side strain before the 2009 Ashes, ended his Test career at 76 matches and 310 wickets. But he continued playing white-ball cricket until 2012 internationally and BBL cricket until 2014, still hitting 147kph for the Sydney Sixers at age 37. For a fast bowler who had never survived a full first class season before Campbell’s intervention, that longevity was the clearest evidence of what the program achieved.
Campbell’s work with Australian fast bowlers continued beyond his national team role. In 2017, he co-founded the BOWLFIT app with Mitchell Johnson, who never sustained a single soft tissue injury across his 10-year international career under Campbell’s conditioning methods. The app delivers the same programs Campbell used on McGrath, Lee, and Johnson to young fast bowlers worldwide.
Campbell remains active in cricket conditioning, training over 50 cricketers from juniors to internationals through his company Jock Athletic. His assessment of modern workload management reflects how much the landscape has changed since his time with Australia, when conditioning decisions involved two people and the head coach rather than the large support staff structures used today.
The conversation between Campbell and Lee was a small moment. A conditioning coach telling a fast bowler what his body could not do, and the fast bowler trusting him completely. It sat at the foundation of a career that produced 310 Test wickets, 380 ODI wickets, and speeds no Australian has matched since.
