Hundreds of fitness fanatics will be hot-footing it to Wandsworth Common tomorrow to attempt to smash the Guinness World Record for the most people performing squat jumps simultaneously for one minute.
To break the record 250 participants will need to take part, and a whopping 600 people have already registered for the mass workout.
The muscles behind the operation are British Military Fitness, providers of some of the UK’s most hardcore outdoor bootcamp classes.
The event is part of National Outdoor Fitness Day, which is encouraging more people to take their exercise out of doors.
Harry Sowerby, Managing Director of British Military Fitness, said: “People often associate exercise with slogging away in a stuffy gym, but it doesn’t have to be that way.
“There are so many fun ways to get involved in exercise in the great outdoors, whether that’s going on a walk around the park, riding a bike or taking part in an outdoor exercise class.”
“I’m hoping that on this year’s National Outdoor Fitness Day, more people will come and join us for a fun fitness session outdoors – see you in the park!”
After the record attempt, anyone whose legs are not too tired can then take part in British Military Fitness’s biggest ever outdoor workout free of charge.
Anyone interested in joining the record-breaking squat jumpers should register here then head to Wandsworth Common, opposite The Hope pub, at 9am tomorrow.
