A FAMOUS stand-up comedian surprised fitness fans getting a sweat on when he arrived at a leisure centre ahead of his big show.

TV star John Bishop popped into Colchester Leisure World’s gym, off Cowdray Avenue, before his performance tonight.

The funny man from Liverpool is performing at Charter Hall as part of a few warm-up performances ahead of his Right Here, Right Now tour.

He joined resident personal trainer Chrissy Foreman, who posed for a quick snap with the star, before going back to work outs.

Earlier this year, the 54-year-old announced he is to appear in Doctor Who in the role of Dan, a companion to the doctor.

The series will also star Jodie Whittaker, who has played the lead role in Doctor Who for three years, although series 13 is set to be her last full series.
