The Keep Fit Brigade is the team of exercise members at Fred Scuttle's Health Farm. Founded by Scuttle as health courses at popular prices (300 British guineas or $1575 for four weeks), the facility includes exercise and meals consisting of suet dumplings, Yorkshire pudding and treacle and custard. The living quarters are segregated with the men and women joining for exercises (and in the sauna), according to Scuttle.

Exercise includes marching on the grounds, following a female instructor (Jenny Lee-Wright) followed by aerobics (Roy Scammell and Malcolm Weaver) and instructions in unarmed combat. Scuttle sometimes chases after the female guests (Bettine Le Beau and Jenny Lee-Wright), although the mail guests (Bob Todd), get just as distracted. The men also play American football on the grounds. Scuttle also attempts to show displays of his strength when not hitting the punching bag. He also tries to teach boxing unless he gets punched by a female guest (Mia Martin).
