Intervention Criteria	GMCB	TRAD
Supervised center–based exercise sessions	60 min of exercise (walking and lower body strength training) + 20 min of GMCB counseling	60 min of exercise (walking and lower body strength training)
Supervised exercise month 1	2 sessions/week	3 sessions/week
Supervised exercise month 2–3	1 session/week	3 sessions/week
Supervised exercise month 4	1 session/week	No sessions
Supervised exercise month 5–6	2 sessions/mo	No sessions
Supervised exercise months 7–9	1 session/mo	No sessions

GMCB: group-mediated cognitive behavioral exercise; TRAD: traditional center-based exercise therapy.
