Fundraisers got in a spin while collecting £2,200 for Yorkshire Down Syndrome Group.
Keep-fit enthusiasts took part in a two hour spin class on exercise bikes, followed by an hour of high intensity interval training.
Those taking part in the charity event at MP Fit in Birstall also donned 80s outfits.
Owner Karen Dorr, pictured with Matthew Whitaker, said: “It was torture but great fun. We also had an 80s quiz and if you won, you were given a three minute rest. It was a really good event.”
Mrs Dorr also thanked everyone who attended and helped raise the funds.
