Rio 2016 medal hopeful Robbie Renwick reveals how waxing off all your body hair can gain swimmers the fractions of a second needed to win Olympic gold.

The 27-year-old said "It's one of those things you have to do in swimming because you're in a fluid you must offer as little resistance as possible so you have to shave off your body hair."

Renwick also fields questions from javelin star Goldie Sayers, cricketer Ryan Sidebottom and 5 live's Eleanor Oldroyd on "how much time he gains by being completely fuzz free?" and "How much does shaving his legs take off his time?"

Former England bowler Ryan Sidebottom adds that's whilst he'd never shave before a match, he claims infamous Yorkshire CCC dressing room prankster Joe Root has tried to catch him with the waxing strip.
