A group of seven fitness instructors are holding the three-hour fitness event in Glasgow's Barrowland tomorrow.
The team is part of Movin&Giving, which was set up three months ago to help communities and local causes. The fitness fanatics are appealing for more people to come along to the class, which is being held from 2-5pm.
It is free to enter but participants are urged to donate to the Clutha Appeal Fund, which was set up in the aftermath of the tragedy, which claimed 10 lives.
Gemma McNaughton, 30, a Zumba instructor from Paisley, said: "A lot of people have been affected by the tragedy. People want to come out and support the families so this event gives them a chance to do that."
The other instructors - Claire O'Neill, Cheryl Stevenson, Maggie Green, Heather Graham, Samantha Colhoun and Toni Trodden - come from Paisley, East Kilbride and Ayrshire.
Gemma added: "Some of the victims came from the areas we are from so we did feel we wanted to give something back. And as it's the New Year people want to kick start their fitness routine."
A total of 500 people can come to the event.
