Les Mills launches toolkit to help women stay active throughout their menstrual cycle
Menstruation can make it tough to maintain training habits, with 79 per cent of women skipping workouts when their period starts

Les Mills has launched a free toolkit to help women stay active and get the most from workouts throughout their menstrual cycle.
The world leader in group training has designed a series of workouts and educational resources to navigate the physical and mental effects of the menstrual cycle, guided by the principles of “cyclical training”.
The impact of menstruation on training is far-reaching and significant. Three-quarters of female athletes suffer negative side effects based on their cycle – a figure thought to be even higher among non-athletes – while 79 per cent of women take a day off exercise when their period starts.
Cyclical training helps women tailor their training schedule to match the different phases of hormonal activity throughout the month. The technique, Les Mills argues, could support stable training habits before, during and after menstruation, as well as unlocking the hidden benefits.
“We want to make it easy for people to adjust their training and nutrition throughout the menstrual cycle,” said Les Mills chief creative officer Dr Jackie Mills, a nutrition specialist and former obstetrician.
“Understanding the influence your cycle has will allow you to unleash your full potential and really get the most out of your training. It’s going to make things so much better for your mind and your body.”
The menstrual cycle is divided into two phases, the follicular and luteal, with each having unique effects on the body. Les Mills presenter and cyclical training fan Kaylah-Blayr Fitzsimons-Nu’u says the oestrogen spike that occurs in week two makes it the perfect time to crank things up.
“I feel really strong. I train heavier with my weights and add in a LES MILLS Sprint or GRIT. I’ve even found myself able to increase my chin-up PBs on week two,” she explained.
She’s equally philosophical about the days she has to taper her training to be kinder to her body and mind, noting that the focus should be on movement.
“It’s all about adjusting the intensity to suit the day of your cycle,” the presenter added.
“The great thing about cyclical training is it’s so intuitive. You reap the endless benefits of being active, while staying kind to yourself and attuned to your body’s needs as you progress through the month.”
The full range of cyclical training workouts is free to access on the LES MILLS+ streaming platform.

Menopause
Non-hormonal menopause pill approved for NHS use

A new daily menopause pill approved for NHS use could bring relief to women with debilitating hot flushes and night sweats.
Around 500,000 women are expected to be eligible for the treatment, which experts say could help those unable to take hormone replacement therapy, or HRT.
The drug, fezolinetant, also known as Veoza, is a daily non-hormonal tablet designed to target the brain signals that trigger some of the most disruptive menopause symptoms.
In final draft guidance published today, the National Institute for Health and Care Excellence recommended the 45mg tablet for women experiencing moderate to severe hot flushes and night sweats.
More than two million women in the UK are thought to suffer these symptoms during menopause, often beginning during the earlier stage known as perimenopause.
For many, the effects are severe, disrupting sleep, affecting concentration and straining relationships. In some cases women are even forced to cut back on work.
An estimated 60,000 women in the UK are currently out of work or on long-term sick leave due to severe menopause symptoms, costing the economy roughly £1.5bn a year.
Research also suggests one in 10 women has left the workforce entirely because of a lack of support.
