As any personal trainer will tell you, it's very important to warm up sufficiently before undertaking any kind of exercise. But Imogen Thomas took the concept of limbering up slightly too far today as she prepared for her morning jog. The 29-year-old model was clearly aware that she was being photographed as she bent and stretched in the middle of a London park. Wearing a cropped T-shirt baring the face of TV character Keith Lemon, and a tiny pair of pink shorts, Imogen looked very toned as she warmed up in front of the cameras. From bending over with her hands on the floor to kicking her leg up in the air, Imogen did everything she could to ensure that every single muscle was ready to be used before she embarked on the gentle jog. And Imogen's park antics certainly attracted the attention of a few passersby strolling through the park, with one person actually having to step around Imogen as she stretched out her inner thigh muscle.
