Bikram Yoga involves hours of body-bending exercises in rooms heated to a furnace-like 43 degree C, reports the Sun.
At this temperature, the muscles can stretch far further than they usually do, which means fans like Murray can work their bodies super-hard.
Murray, who headed to Wimbledon yesterday to practise ahead of his first match tomorrow, has also put his success down to his gorgeous girlfriend of four years Kim Sears.
The British tennis star is confident of a good show at this year's Wimbledon and is optimistic about his chances of claiming the first grand slam title. (ANI)
