A miniature weight has been designed to help people improve the strength of their thumbs.
The ‘Thumbell’ was designed after new research revealed that 26 million Britons suffer thumb pain because of too much gadget use.
The survey, commissioned by O2, found that 43 per cent of people have had thumb pain in the last five years.
The fitness tool is currently being trialled by staff to ensure their thumbs are ready for when the company goes 4G, as part of O2’s ‘Fit for 4G’ campaign.
The idea of the campaign is to strengthen people’s thumbs and fingers before they switch to 4G as the faster operating speed will mean their digits are put under even more pressure to work quickly.
