To win gold at the Olympics athletes are constantly looking at ways they can speed recovery from their gut-busting schedules.
Massage and physio are the most widely used techniques but now a new practice based on traditional Chinese medicine has been thrown into the spotlight after the world's greatest Olympian, swimmer Michael Phelps appeared with strange circles on his torso.
Tristram Clayton experiences the ancient art of 'cupping'.
The idea is not new and has been used by Kiwi athletes before, most notably Sonny Bill Williams.
Williams shared a photo of him undergoing cupping with the caption "Detox time" with his 500,000 social media followers last November following the Rugby World Cup.
