I came to coaching by first correcting my own training, slowly and with a good deal of trial and error. What became clear along the way was that most of the advice available is written for someone whose circumstances bear little resemblance to those of the people reading it.
Working as a personal trainer means early mornings and late nights, so my own week is rarely the tidy one the textbooks assume. Living that is what taught me to build training around a realistic week rather than an idealised one, and it is why the clients I work best with tend to describe themselves as too busy for structured training.
In most cases they are not too busy. They have simply never been given a plan that took their actual schedule seriously.
That is the work. Training that fits the days you have available. Nutrition that survives a Friday evening. A structured review every week examining what genuinely happened rather than what was scheduled. And at the conclusion, a documented plan for maintaining the result rather than starting again next January.
Away from coaching I cook, I am into music and I DJ, and I spend as much time as I can with family and friends. That matters here more than it might sound: a plan that leaves no room for any of it is a plan you will resent by week three.
