He runs a club called Lumpini (named after the famous boxing stadium in Bangkok) and teaches Thai boxing (of which the more popular kick-boxing is a derivative). The only protective items permitted in a Thai boxing match are 8oz gloves, a groin guard and gum shield. Unlike kick-boxing, the use of knees, elbows and kicks above the waist are all permitted.

Kelly Inkin who has been attending classes for the past three months considers it preferable to the mindlessness of aerobics and says, 'Although I haven't had to use it on the street, my confidence has increased by 100 per cent.'
Lil Lees, press officer of Civic Leisure Ltd, believes that women are less interested in beauty than with ways to develop their bodies. 'Thai boxing,' she says, 'seems to offer them a strength and elegance.' Be warned - this sport does not carry a government health warning, yet.
