“We need a cultural shift in how both sexes view women’s exercise. Time is a major barrier to many women being active: they can feel too caught up juggling work, family and other responsibilities. We need a public messaging campaign about the importance of women finding time for themselves, and men also need to support women in this.

Anything health clubs can do to facilitate this would help – for example, providing childcare so that mums with young children can exercise, running gym sessions and classes where they can bring their children, and organising activities that are suitable for all the family to be active.

Many girls drop out of physical activity during their teenage years, but health club operators could reach out to them with teenage gym sessions, classes and outreach programmes. I’d like to see more innovation from the industry.

Marketing is crucial. I’m a big fan of the This Girl Can campaign, because it reflects what people really look like when they exercise. I’d like to see more of this sort of imagery in marketing campaigns, not the size zero model in lycra doing yoga. Finally, I’d like to see clothing companies making more flattering sports clothes in larger sizes.”

“From our insight work, we’ve learned that lots of women and girls feel judged at sports and health clubs. They feel they don’t belong, either because they’re the wrong size, shape or not wearing the right clothes. We want to take these insights and make sure clubs place them at the heart of their offering.

The easiest and most powerful thing any club can do to become more female-friendly is to ask women who aren’t currently using their facilities what they want. Reach out to former members, the local WI, NCT or colleges and find out why women aren’t coming to your club.

There’s a sharp drop-off in activity during teenage years, which is partly due to interests changing during puberty, but also because at this age sports clubs start focusing on talent; the average ones get left behind. Health clubs and sports clubs need to think about what they’re offering these girls and give the opportunity for teenagers to dip in and out of a range of activities. Unless they’re especially talented, teenagers don’t want to do a single sport. The activities that are growing are those where the user is in control, such as running and cycling. People also want to be casual, so all clubs need to react to that, offering the opportunity to be spontaneous.”

“Talking to women through social media has enabled us to understand what local women want to do and helped us reach out to females so we understand the barriers they face.

In terms of what operators can do to appeal to women, programming is very important. Women are time-poor, so they want things like a 20-minute class at lunchtime, or just before or after work. Timetabling is crucial: classes must be run at a convenient time. A more relaxed and supportive approach to bringing babies and children along is also needed.

Many women are intimidated by gyms because they think they’ll be full of people who look like the women in the adverts. We didn’t use any stock images for I Will if You Will: using local women in our publicity encouraged more people to give it a go.

There are also a lot of important considerations when it comes to facility design and changing room provision. We’ve worked hard with our studio team and deliverers to ensure we offer an encouraging environment at all times, reinforcing the positive messages of I Will if You Will. Providing blinds and screens for women-only sessions gives some females more confidence, and offering female-only sessions – such as learn to swim lessons – has given them confidence to start swimming on their own.”

“It’s to the benefit of our industry to have more women as members. An even gender mix creates a better vibe and the sexes use gyms differently, driving better use of space and equipment.

Our research shows females can struggle with the idea of a gym membership. They often perceive gyms to be intimidating places that are not for them, or that sport generally isn’t their thing. Our member base is currently 40 per cent female and we’re working hard to increase this through our environment – a gender-neutral, light, airy and non-threatening space – and by offering more of what our female members want, such as functional training and group exercise.

We’re partnering with Sport England in an open weekend aimed at women in May, hopefully showing prospects that our gyms are places they can see themselves spending time in. Working out with friends is a great way of motivating repeat exercise behaviour, so we’re encouraging people to come with a friend. Role models are also key to getting people active, and we think female sporting role models are not yet celebrated to the extent of males. To this end, we’re sponsoring the Sporting Role Model award at the Women’s Sports Trust’s inaugural Be A Game Changer Awards.”
