Some good old advice is to imagine an invisible center line down your body and try not to let the arms cross it. Facial as well as neck and shoulders muscles are normal culprits in our running struggle against our own efficiency. Do what I call a cheek-check. Concentrating on muscle relaxation can pay great dividends. Ask any mother, or mother's coach, who has given birth recently.
Relaxation keeps the body running stronger, longer.
