Still maintaining a fairly lean state. Nothing complicated in terms of either training or diet. As I've been saying it is about consistency, patience and persistence. I'm 45 and have been training with weights for 30 years. I am nothing spectacular, but certainly look better and am fitter than most of my 45 year old friends.
My main challenge is keeping that focus on the basics and not being diverted by the glamour of the latest machine or technique.
I am still trying to get stronger because if there is any magic, then that is it - progression. But beyond all this is a desire to keep safe and avoid injury.
Diet? Since getting more sensible and introducing more carbs and less fat, I've leaned out a lot. Not sure if Matt Stone would be happy with me though!
