Keep Fit is a 1937 British comedy film directed by Anthony Kimmins and starring George Formby, Kay Walsh and Guy Middleton. Formby was at his British top box-office peak when this comedy was made.^[1]

George Formby again plays his working class underdog, gormless, gullible, indefatigable and triumphant hero. A weakling, Formby's character overcomes obstacles to beat a corrupt rival in the boxing ring. He plays a scrawny barber's assistant who, in response to the keep fit fad sweeping through Britain at the time, dreams of a better physique, and sings of it in the catchy "Biceps, Muscle and Brawn". He falls in love with a beautiful manicurist, and competes for her affections with a muscle bound thug. The manicurist is more attracted to the brute until the barber can prove that he is a crook, and defeat him in the boxing ring.^[2][3]
