mobility exercises

Drills -- a combination of neuromuscular activations and re-wirings plus very specific strengthening and mobility exercises -- are designed to help develop the co-ordination and strength necessary to run fast with ease. It's a once-a-week session that really helps my running, so I try never to miss it, even though it involves getting up in the middle of the night to be ready to be not just awake, but capable of independent movement, at 7.30am.
