Exercise: Stages of Change (Short Form)

Regular Exercise is any planned physical activity (e.g., brisk walking, aerobics, jogging, bicycling, swimming, rowing, etc.) performed to increase physical fitness.  Such activity should be performed 3 to 5 times per week for 20-60 minutes per session.  Exercise does not have to be painful to be effective but should be done at a level that increases your breathing rate and causes you to break a sweat.


Do you exercise regularly according to that definition?

  • Yes, I have been for LESS than 6 months.
  • No, but I intend to in the next 30 days.

  • No, and I do NOT intend to in the next 6 months.
