Great article.   I ran the London Marathon in 2002, and my non executive director has run it several times.   I recently tried to set up a running club in our HQ, where we share offices with other businesses.  I was shocked at the resistance imposed at the top (obviously by non runners!).  They would not allow their staff to participate in a 30 minute run during the day as it would take their focus away from work.  They need to shower so that would take up more time it was said.   Exercise can help boost productivity at work through alertness. During exercise, you increase blood flow to the brain, which sharpens your awareness and makes you more ready to tackle your next big project. Exercise can also give you more energy. Having more energy means you will feel more awake at work, and of course more productive!
