More than 100 people have signed up to an attempt to break the Guiness World Record for the most number of people doing sit-ups at once.
But there is still time for people to join in with the challenge taking place today (Wednesday) at Corby Town Football Club.
The record stood at 414 people last week, but now Corby will have to do one better as it has since been broken with a new record of 504 people joining in.
The world record attempt will take place at 7.30pm tonight, with participants advised to arrive between 6.30pm and 7pm.
Among those taking part are players and staff from Corby Town FC.
Corby Radio will also be attending to get the crowds going and support the event.
All participants taking part must do continuous sit ups for one minute in order for the attempt to count.
Each sit up must be from lying down on the floor with knees bent and shoulder blades touching the floor, moving to sitting up with elbows touching knees and then lying back down again.
It doesn’t matter how quickly you do them but you must be continuously moving for the full minute.
To sign up as a participant or a volunteer to help on the day simply go to www.leisureoffers.co.uk/corby/guinness.
There is no age limit although participants under the age of 16 years will be required to seek parental permission.
All participants must be able to perform sit ups.
Full terms and conditions are available when signing up online.
