Olympic champion Jessica Ennis-Hill has introduced a new wellness app, developed to help women create an exercise regime based on their natural period cycle.

Called Jennis Cyclemapping, the app is designed to create a bespoke fitness programme for women with a natural period cycle, incorporating their unique patterns, symptoms and personal goals.

Created with the help of physiologist, Dr Emma Ross, each programme is personalised to the user's unique cycle and allows them to plan their sessions, with daily recommendations based on their hormones, energy levels and mood.

When users sign up, they go through a questionnaire which helps the app understand the user's fitness goals, cycle length, period and pre-menstrual symptoms and fitness levels.

From there, the app is able to pinpoint where the user is on their cycle and make training recommendations based on the hormone profile of the phase that they’re in.

Each day, the app will recommend a different selection of workouts – ranging from HIIT, strength, yoga, LISS and audio HIIT runs to recovery sessions.

All sessions are between 5 and 35 minutes in duration.

Ennis-Hill said: "I've been in sport my whole life, but it was only towards the latter part of my career that the science of matching your workouts and diet to your menstrual cycle was being touched upon.

“We’ve created Jennis CycleMapping because this information is essential to women’s health, but isn’t accessible or widely talked about.

"By opening up the conversation and making it easier for women to understand their cycles, my team and I want to help women all over the world feel better, train better and understand their bodies better.

"Jennis CycleMapping maps the right fitness sessions to the four phases of the menstrual cycle so that women get bigger training gains, improved energy, reduced PMT and optimised hormonal health.

"Using the app, women can get a personalised monthly programme that adapts to their cycle, symptoms and goals.

"Users can enjoy world-class coaching sessions and also get expert daily insights that help them feel great, eat smart, get stronger and sleep better."

Jennis Cyclemapping is the latest app launched by Ennis-Hill and adds to her portfolio of fitness training, pregnancy and postnatal-related apps.

Each app creates exercise regimes specifically designed for women at different times in their lives and are all priced at £14.99 per month.
