Arm Intervention/treatment
Experimental: Telephone-linked Communication (TLC)
This group will receive the computer-based telephone counseling.
Behavioral: TLC
Computer-based telephone linked communication will be used to counsel subjects to adhere to their exercise program over time.

No Intervention: Control
This is the control group. They will receive the exercise class, however, they will not receive the telephone counseling.

Primary Outcome Measures :
  1. Self-report measure of exercise adherence over the last 3-months on a numeric rating scale [ Time Frame: 24 month ]
    Exercise adherence was assessed by the single self-report item "How would you rate your level of adherence to the prescribed BOOST exercise program, over the last 3 MONTHS?" Participants selected a number from 0 (not at all) to 10 (completely as instructed). Higher scores reflect better adherence.

Secondary Outcome Measures :
  1. 24 -month change in self-report of pain and function using the WOMAC index [ Time Frame: post the 1-month exercise class, 24 months ]

    The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is a self-administered questionnaire consisting of 24 items divided into 3 subscales:

    Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright Stiffness (2 items): after first waking and later in the day Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in/out of a car, shopping, putting on/taking off socks, rising from bed, lying in bed, getting in/out of bath, sitting, getting on/off toilet, heavy domestic duties, light domestic duties Responses to individual questions [between 0 (extreme) and 4 (None)] are summed to a raw score ranging from 0 (worst) to 96 (best) and then normalized to a WOMAC Score of between 0 (worst) to 100 (best). The difference in pain and function subscale values between the measures following the exercise class and the 24-month follow-up were used for secondary outcomes.

  2. Quadriceps strength [ Time Frame: Change in quadriceps strength from baseline to 24 months. ]
    Isokinetic quadriceps strength will be assessed with a Biodex

  3. Timed Physical Function tasks [ Time Frame: Change in timed physical function task over 24 months ]
    Timed physical function tasks will include a timed get up and go, timed stair ascent and descent, and a 5 and 10 chair stand time. We will examine the association of adherence, as a dichotomous and continuous variable, to change in timed physical function using logistic and linear regression, respectively.

  4. Exercise quality [ Time Frame: Average measure of exercise quality over 24 months ]
    The outcome will be assessed at the end of the 24 month follow-up period as the number of calendar periods (1 month per calendar period) that the participant exercises at least half the number of prescribed sessions (a minimum of 6 out of 12 over a 4 week period) with the agreed upon level of intensity.
