Jenna Armstrong

Jenna Brynn Armstrong’s fitness career began in 2018 after she quit her day job at MGM Resorts Department of Government Affairs to teach yoga. In addition to teaching studio classes from Las Vegas to DC, she’s led meditations for conferences and corporations, held classes at the Departments of Justice, Commerce, and Energy, as well as at the White House Athletic Center. 

Jenna’s passion for movement has centered around resetting the mind through exercise. Her classes will have you so engaged in your body’s current action, the stress of life fades away. The exercise program Joseph Pilates created supports this philosophy. Recognizing the need for Classical Pilates in the Seacoast New Hampshire area, Jenna created Refined Resistance. Experience the mental and physical health benefits of the authentic Pilates method.
