And I felt great , ’ she added .

Miss Balding back in 2012 before her health kick which sees her regularly exercise and diet , and right , on the cover of Woman & Home . And it highlights just how much her shape has changed in recent years , after a bet with her mother spurred on to get in shape . She had caught sight of herself looking ‘ as if I ’ d been blown up with a bicycle pump ’ , she once said , on a TV monitor at the Newmarket races in 2013 . Miss Balding was spurred to get in shape after a bet with her mother , offering £100 per pound of weight shed to whoever lost the most . She used a Jawbone fitness band to count her steps , which she said made ‘ a massive difference to my life ’ . She walked 10,000 steps per day , monitored by a calorie-counting app , and went on a diet – although she has admitted not sticking to the 1,200 calorie limit . And the result was a 20lb weight loss in the space of two-and-a-half months . Tomorrow Miss Balding ’ s new entertainment and sport chat show begins on BBC2 . The channel acquired the rights from BT Sport and the programme will be screened on both channels .
