Brief Summary
This study evaluates whether participating in a home-based exercise program leads to lower levels of complication rates and patient-reported disability after surgery. Half of the participants will be randomized into the exercise group, while the other half will be randomized into the control group.

Outcome Measures
Primary Outcomes (2)
In-hospital complications
The Postoperative Morbidity Survey (POMS), will be used to define complications. Individuals experiencing any POMS complication or dying in hospital will be said to have experienced a complication.
up to 30 days.
Patient-reported disability 30 days after surgery
The World Health Organization Disability Assessment Schedule 2.0 (WHODAS) will be used . It is a patient-reported disability scale that assesses limitations in six major life domains - cognition, mobility, self-care, social interaction, life activities and participation in society. Participants will report if they have had no difficulty, mild difficulty, moderate difficulty, severe difficulty or extreme difficulty (simply cannot do) with the items listed.
Assessing change in score from baseline data collection to 30 days post-op
Secondary Outcomes (12)
Function - 5 Times Sit to Stand
Assessing change in score from baseline data collection up to 30 days post-op.
Function - Daily and total step count
Assessing the difference in daily and total step count between the exercise group and control group for 30 days post-op.
Function - Katz Index of Activities of Daily Living
Assessing change in the participants KATZ ADL score from baseline to post-op day 3, 5, 7 and up to 30 days.
Function - Falls
Assessing the difference in the occurrence of falls between the exercise group and control group on day 3, 5, 7, up to 30 days, as well as 30-day, 90-day and one-year after surgery.
Health-related quality of life
Assessing any change from baseline to 30, 90 and 365 days post-op.

Study Arms (2)
Exercise Group
EXPERIMENTALThe intervention is a home-based, multimodal exercise prehabilitation program. Exercise is prescribed in one-hour sessions, performed a minimum of three times per week for three weeks, consisting of: 1) strength training, 2) aerobic exercise and 3) flexibility. The intervention group will receive weekly phone calls to gauge adherence, suggest modifications, provide support and track any adverse events.
Control Group
NO INTERVENTIONThe control group will receive the World Health Organization recommendations for physical activity for people greater or equal to the age of 65 years old pamphlet, as well as a guide to healthy eating for older adults.
