Welcome to Jennis

Created with leading experts in women’s hormonal health, Jennis CycleMapping empowers women to truly understand their bodies and hormones, then shows you how to train, eat and sleep for optimised hormonal health.

It’s time to move with your hormones, not against them.

The best-kept secret in every woman’s life is the power of her own body. It’s time to let the secret out.

* Only 4% of medical studies are done exclusively on women and most training programmes are created for the physiology of men and a 24-hour cycle.

Jess Ennis-Hill, Founder

As one of Great Britain’s most successful athletes, Jess Ennis-Hill spent years working and training with the best physios, physiologists and psychologists in the world. When she retired from professional athletics, she wanted to share everything she had learned across her career and make it accessible to everyone. The result is Jennis, a game-changing training programme that helps women train, eat and sleep for optimised hormonal health.


Emma Ross, Head of Physiology

Physiologist, Dr Emma Ross, is on a mission to help women tune in to what’s really going on in our bodies, deciphering hormonal changes and helping you work with your menstrual cycle to feel better, train better, rest and recover better. Before working with Jennis, she was Head of Physiology at the English Institute of Sport, where she worked with female athletes in the run-up to the Rio Olympic games.
