Her study of the benefits of eccentric stretch training has also been the basis of the pledge documentaries Aging Backwards and Forever Painless airing on PBS public television.

[1] Her mother, Anstace Esmonde-White, and father Larry were the hosts of From A Country Garden,[4] a public television series produced by WPBS-TV that ran on PBS for seventeen years beginning in 1986.

[5] Esmonde-White began her career studying to become a ballerina[6] at Canada's National Ballet School[7] co-founded in 1959 by Celia Franca and Betty Oliphant in Toronto, Ontario.

A photo in Dance Collection Danse shows her classmates and a young Esmonde-White smiling up at the violinist Yehudi Menuhin after his concert at Massey Hall.

[8] After her training, she worked around the world with the National Ballet of Canada at the same time that the company danced with Margot Fonteyn, Rudolf Nureyev, and other very well-known dancers such as Karen Kain and Robert Joffrey.

[9][10] Esmonde-White's next effort, her own company making homemade rag dolls, led to her becoming an executive at the toymaker Hasbro, but business trips kept her away from her child, who was then five years old.

[11] It took a while for the idea of strengthening the muscular system by lengthening muscles to catch on in fitness circles, but eventually she prevailed, asking her students to exercise for about 22 minutes every day.

Her daughter Sahra designed and found funding and crews to make a workout video with Esmonde-White that has been seen in many countries including Canada, Costa Rica, Guatemala, Mexico, Panama, Greece, India, South Africa, and the United States.

Designed for people who have been treated for breast cancer, the workout can increase the range of motion of the arms and shoulders after a mastectomy and prevents lymphedema.

[9] The longest-running professional ice hockey team in the world, the Montreal Canadiens, are followers as are students from the school of Cirque du Soleil.

[20] Sahra holds Essentrics sessions once or twice a week for the Canadiens during training camp at the suggestion of Pierre Allard, their strength and conditioning coach.

[21] Esmonde-White has worked with a number of prominent Canadian athletes: Sports Hall of Fame diver Alexandre Despatie, synchronized divers Meaghan Benfeito and Roseline Filion,[10] Olympic gold-medal goalie Kim St-Pierre,[15] squash player Jonathon Power, figure skater Joannie Rochette, and pairs champions Jessica Dubé and Bryce Davison.
