Dr Grump's exercises for cold weather

The best exercise in these circumstances is a little weight-lifting: something the size of a wine-glass, lifted not too far, and very gently: up to the lips, hold, and down again. Eight repeats or so.

This may be followed by the book curl: lie on the floor and, propped up on one elbow, position book in front and hold.

She also recommends the Thorntons jaw revitaliser: using a pincher movement with preferred hand grasp either an Alpini or Diplomat chocolate (or, for those requiring a high-impact workout, a finger-sized piece of special toffee). With a slow steady movement bring chocolate to mouth, place in mouth and chew. Proceed until box is empty.

If this regime is closely observed during the entire festive season Dr Grump guarantees a much augmented figure.
