Another new study says not enough diabetics are doing a key part of controlling their diabetes.
The study says the majority of diabetics do not exercise.
The survey of more than 23,000 diabetics found only 39% of them exercised at least three times a week.
The same study found 58% of non-diabetics exercise at least three times a week.
The American Diabetes Association recommends diabetics get at least 30 minutes of aerobic exercise a day, five times a week.
