Even though I played quite a bit of sport, Aussie Rules during winter, Cricket during summer and golf all year round, I partied hard and my diet was pretty terrible, I relied and got by more on natural talent than my physical prowess, luckily for me at the time it was enough to get by and get the job done in my chosen sports, then as I got older I did want to do better, so started training harder and hitting the gym and looking after my diet more.
The hardest was retraining myself to play football at a lighter body weight, but found I had a heap more run in me and more spring, then I did my ACL twice in 3 yrs and it was all over
