"The best trainers and coaches of all time find and fix weaknessess. The rest simply focus on strengths".
That's a quote from a well known physical therapist.
And I imagine I'll never be the best because it's the athlete's strengths I focus on first during rehabilitation & return to play. Set them up for success by finding that athlete's comfort zone & using it as my starting point. Gradually expanding their envelope of function by monitoring them both intra and inter workout; and making adjustments.
