Best excuse yet for not going to gym
Going to the gym may not be as beneficial as you think because some fitness fans' poor hygiene could leave you ill.
Almost half of those polled by Nuffield Health admitted using something in the gym that didn't belong to them, including towels and water bottles.
Nuffield warned the behaviour could leave people open to catching colds and flu from other gym users, as well as fungal infections like athletes foot.
Sarah Marsh, the firm's professional head of fitness and wellbeing, said: "Not wiping down gym equipment can help germs spread. These germs can cause not only vomiting and diarrhoea but also respiratory infections."
The survey of 2,000 people also found that 22pc of people were put off exercise by poor hygiene or excessive nudity in changing rooms.
