Every manufacturer has three words printed across its Research and Development laboratories - 'Club Head Speed'. You are sold every new club and ball on its Tour performance advertising and that is all about what happens to a golf ball when the club head is moving very fast.

If you asked the 156 players who tee it up each week across the globe for all that money, what would be the one thing they could not no do without, the huge majority would say their Tour physio vans and the experts who man these mobile flexibility factories.

Every little bit of extra clubhead speed give a few more yards but this is nothing about snapping wrists (not literally) as you hit the ball. Its all about hip speed and having the posture to make your swing arc wide, fluid and consistent.

Steven Harris is the man behind BodyGolf. A chartered physiotherapist since 1983, Harris found his interest in the biomechanics of the golf swing when he set up his Sports Injury Clinic in 1988, at Tamworth, just down the road from the De Vere Belfry.In 2003, he launched 'The BodyGolf Exercise Programme' and this new DVD set takes those years of experience and brings them to any golfer.

Harris shows any golfer the key areas of flexibility they need to work on, through a set of 'tests' which are simple stretches where Harris provides a guide as to what is good flexibility and what needs work. Using a varied set of demonstrating models (notably in age and in physique - and a lady) the DVD's second section demonstrates how to improve any areas of poor performance. It finishes with a more general guide to being fitter and stronger, especially for golf.

What about the presentation and usability of the DVD. The Professional endorsing the video is Paul Broadhurst, who will go for third Portuguese Open title next Spring. Broadhurst now hovers around the 50s in the World Rankings after a few years when many thought his winning days were over after injury and poor form.

What Broadhurst has achieved using BodyGolf isn't continually plastered all over the DVDs. The use of different ages and shapes of model, and some very good swing illustrations, are there to show any golfer that flexibility is something they really ought to consider

Its not a simple matter of just looking at one part of your body, even though many people's lower back flexibility is poor (to say the least), so the numbers of tests and exercises could be a problem.

The layout of the DVD and the simple navigation is an excellent way of keeping interest in what actually amounts to new routine and work for the user to gain the benefits.

Most of us amateur golfers spend our working weeks sat behind desks and computers - a recipe for poor posture and flexibility. BodyGolf is one of the best answers for how we all can arrive on the tee for a weekend's golf with a much better chance of being longer, straighter and much more consistent.

Its technical stuff, well presented and very useable, especially with help. There are the required warnings about seeking advice and exercising caution when using any fitness related video, but for anyone who is starting from a low level of flexibility and fitness, working with a physio or good personal trainer would be very sensible.
