"Week 1: Patients will undergo an introductory session where the occupational therapist will assess the general condition and physical fitness of the subjects.~Week 1 to Week 12: Group exercise sessions supervised by a physiotherapist, twice per week, each session lasting 1 hour, with no more than 8 participants in each group exercise session. The exercise regimen for each session will be personally tailored for the subjects, and will include stretching, cardiovascular and strength training, and cooling down exercises.~Week 12 onwards: Patients will receive phone calls- monthly for the first 6 months and then 3 monthly up to the 2-year mark, to encourage them to continue with their exercise regimen at home."
