Sir Paul McCartney was arm in arm with wife Nancy Shevell as they paid a visit to a north London fitness studio on Thursday morning.
The veteran former Beatle, 75, went some way towards proving that age is just a number by stepping out in jogging bottoms and trainers ahead of a workout with Nancy, 58.
Staying warm beneath a tracksuit top and thick quilted coat, Sir Paul was in characteristically high spirits while strolling alongside his American wife. Joining her husband, Nancy looked ready for her own workout in hooded top, blue leggings and trainers.
