Men who exercise regularly can last twice as long in the bedroom, according to a study.
Those who jogged, cycled or lifted weights for 40 minutes each day lasted around five minutes 30 seconds, on average.
In comparison, men who walk for less than 30 minutes a week last an average of three minutes, with one ejaculating in just 20 seconds.
Turkish researchers found premature ejaculation was more frequent in those with a sedentary lifestyle.
‘It can be assumed that regular physical activity may be effectual in gaining a sexual life of higher quality’, the researchers, led by Dr Yildiray Yildiz, wrote.

Nearly 250 participants were divided into two groups – based on how much exercise they usually took part in.
The volunteers were 18-45 years old, of same ethnic origin, same location and were monitored during sex for at least six months.
Participants and their partners used a stopwatch every time they had sex, starting it from the time of vaginal penetration until ejaculation of semen.
Scientists from the Ankara Training and Research Hospital also asked the men how satisfied they thought their partners were after sex.
In group of men who exercised regularly, three quarters (76 per cent) of the men believed their partner was completely satisfied.
This figure dropped to just 56 per cent in the group of sedentary men, according to the research published in the Urology Journal.
In an analysis of the duration the men lasted, none of those in the exercising group experienced what is defined as premature ejaculation.
However, 27 per cent of people who didn’t exercise experienced what researchers defined as premature ejaculation.
Men in the exercising group lasted from just two minutes to 25 minutes. While men in the sedentary group lasted from 20 seconds to seven minutes 50 seconds.
The International Society of Sexual Medicine (ISSM) defines premature ejaculation as occurring within one minute of penetration.
The NHS says PE falls into two categories – primary or secondary, based on whether men have always had the issue or it recently developed.
The causes of primary premature ejaculation are often psychological, such as having a traumatic sexual experience at an early age.
Secondary premature ejaculation can be caused by both psychological and physical factors and has been linked to drinking too much alcohol.
The condition, experts say, causes stress, discomfort, distress, and even avoidance of sexual intercourse in the individual.
A number of other scientific studies have also investigated the link between erectile dysfunction and exercise.
Researchers from New England Research Institutes, Massachusetts in 2000 found that those who take part in daily exercise of less than 200 calories a day have been associated to having erectile dysfunction.
The risk of erectile dysfunction reportedly decreases by 70 per cent in those who increased regular physical activity in their daily lives.
