The Programme, final week: Trainer's comments on Sarah

Lynne Wardle: Sarah has achieved a lot in a fairly short space of time. She has reduced her body fat and weight significantly and also increased her performance in a number of areas. Particularly notable are her results for abdominal crunches and press ups, which are difficult exercises and demonstrate an increase in both her core stability and strength.

Interval training has had a positive impact on Sarah's aerobic fitness – from walking at the outset, she now combines walking and running in each session. Going forward, if Sarah maintains the same level of activity and focus, she will continue to feel the benefits of a healthier lifestyle.
