Wayne Goldsmith overstates as always. But he’s correct on this point:
… a workout which engages the heart and mind of every athlete so that all activities are performed with passion, precision and perfection is a great workout. …
Engagement can be defined as the ability of a coach to create a performance environment where every athlete wants to give more than can reasonably be expected.
Motivation is the desire: the fire that drives an athlete towards a goal or achievement.
So, the key to great coaching is not sports science and it’s not actually coaching per se: it’s providing athletes with the environment and opportunity to express their engagement and motivation through their training: through the way they complete their workouts. …
Contests, games and short term objectives can make training more motivating.
