Jessica Larson of Greenbank is the winner of the 2013 Fall Fitness Challenge at Island Athletic Club.

Larson, 29, completed the challenge, which lasted eight weeks. She lost 21.4 pounds in the fall challenge.

Larson shed 5.8 percentage points of body fat while working with club trainer Jane Gerlach. She reduced her waist  measurement by 4.5 inches and toned her body while maintaining healthy, lean muscle mass.

The club’s annual Fall Fitness Challenge links participants with the club’s certified personal trainers, who work closely with each individual to create diet and exercise habits that result in healthy, sustainable weight loss and fitness improvements.

Larson’s accomplishment comes a year after she participated in the club’s 2012 Challenge, when she lost 27 pounds. Larson maintained her weight in the ten months between the two Fall Fitness Challenges. Larson has lost over 47 pounds since September 2012.

As 2013 champion, Larson was given the option of two prizes – $300 in cash, or $600 in personal training. To demonstrate her commitment to health and fitness, Larson chose the training.
