2x(10x40secs in Zone 5) with 20secs rest between reps and 4mins jog recovery between the two sets.

Phil Mosley
My Pro Coach

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

My training plans are intelligently designed around a typical work week. I set proven, time-efficient higher intensity workouts in mid-week, with longer aerobic workouts at the weekends.
