I have been doing the warm-ups at Wimbledon tennis qualifiers for many years. Indeed some of the young things I worked with back in the day are now 40+. I have introduced hundreds of people to yoga this way and hopefully a few will have picked it up from "Yoga Mama" Here is the lovely group from this year's event busting their yoga moves. Many tops sports people now use yoga as part of their training programme and, indeed, many top tennis players use yoga to increase flexibility, strength and mental focus. Who? My lips are sealed.
