My Pro Coach

I have 20 years experience of helping amateur athletes surpass their goals, while still making sure they have quality time available for family, friends and career. As a parent who works for a living, I know how challenging this can be.

My training plans are intelligently designed around a typical work week. I set proven, time-efficient workouts in mid-week, with longer aerobic workouts at the weekends. This gives you the structure and consistency you need to continually improve.
