Strictly Come Dancing star Ashley Roberts and DJ Locksmith from dance music group Rudimental have been added to the long list of high-profile supporters of this year's National Fitness Day (NFD), which takes place in September.

Both Roberts and Locksmith – real name Leon Rolle – are passionate about fitness and as National Fitness Day ambassadors, they will look to raise the profile of the event and to inspire more young people involved in activities. The pair join a lineup which already includes legendary ballerina Dame Darcey Bussell and Paralympic champion Baroness Tanni Grey-Thompson.

Taking place on 25 September, National Fitness Day is held annually during the European Week of Sport and celebrates the benefits of physical activity for health, happiness and wellbeing. The event is coordinated by health body ukactive and supported by AXA PPP healthcare.

The day will see thousands of activities take place across the UK and this year's event will kick-off with a workout for residents of the Royal Hospital Chelsea in London, with Dame Darcey Bussell leading the Chelsea Pensioners through one of her tailored DDMIX sessions.
