Girls Aloud star Cheryl Cole works out with boyfriend Derek Hough
Cheryl, 27, used the treadmills and did some crunches during the session.
‘She hasn’t been able to exercise in over 2 months and it’s been frustrating the hell out of her,’ a source tells the Daily Mirror.
‘Now she’s feeling better, she is desperate to start boosting her cardiovascular fitness.’
The X Factor judge Cheryl contracted malaria while on holiday in Tanzania with Derek in June.
