Tyler Stewart of The Barenaked Ladies has his own challenge for Toronto mayor Rob Ford and his attempt to lose weight.

The challenge was posted on YouTube.

The mayor and his brother, Councillor Doug Ford, launched their city-wide weight-loss challenge with a public weigh-in at City Hall Monday.

Stewart, the drummer of The Barenaked Ladies, works out at a Toronto gym called the Motion Room and asked Ford to join him there for a workout.
