A tradition on the day after Thanksgiving is working off the Thanksgiving meal.
At Pinnacle Athletic Club in Mishawaka Friday, business was up about 20% over a "normal" Friday.
From stationary bikes to weightlifting to racquetball, people are doing what they can to maintain or get back into shape.
Jim Bradford of the Pinnacle Athletic Club said, "What motivates them? Well, I think what they ate the day before."
Bradford added, “Blame the turkey, blame the stuffing, yes. We can always talk bad about that, but today's the day we start doing something good about it."
Bradford says the change in the weather also helps motivate people to step-up their workout.
