Hundreds of people took part in a gruelling fitness session organised by British Military Fitness.

About 172 people showed up to the class in Clapham Common last Saturday to try and kick-start their New Year's resolutions.

The free taster event was carried out by trained instructors who are serving or former members of the armed forces.

Instructors help motivate participants, while making sure they have fun during the class.

Tasters sessions also took place in London, Birmingham, Leeds and Manchester and are suitable for people aged 18 to 70.
