The participants selected for the teleprehab arm will undergo a supervised 8-week multi-modal exercise program in a telehealth format (using doxy.me, a free telehealth platform) delivered by licensed physical or occupational therapists who have undergone cancer specific rehabilitation training within Select Medical's ReVital® cancer rehabilitation program. Participants will attend teleprehab sessions 2 times per week for a total of 16 sessions.

The participants randomized to the attention control arm will not undergo an exercise regimen, but will be contacted by the study staff on the phone once a week..

Participants will undergo a total of 16 sessions over 8 weeks. Each therapy session will comprise of patient education, including facilitated goal planning, promotion of physical activity and safe exercise guideline, followed by 30 minutes of preferred aerobic activity such as walking or biking.

Participation rate will be measured as the number of participants agreeing to participate in the study divided by total participants approached for the study.

Completion rate will be measured as the number of participants completing the study intervention phase (8 weeks) divided by the total number of participants starting the intervention.

Adherence rate will be computed Number of participants attending at least 80% of the planned intervention sessions divided by the total number of participants initiating the intervention.

Acceptability of intervention will be measured using a) 9-item Theoretical Framework of Acceptability Questionnaire which measures participants perspectives on the acceptability of the study intervention. Responses are measured in a likert type scale. and b) a semi-structured interview that will be focused on gathering overall acceptability of the intervention to the participants. Interview questions will be focused on understanding participants perspectives using 7 different proposed constructs of acceptability, i.e affective attitude, burden, ethicality, intervention coherence, opportunity costs, perceived effectiveness and self efficacy.

Investigators will measure lower extremity physical function using the Short Physical Performance Battery Scores (SPPB, score 0-12; higher score indicates better physical function) and compare the difference in SPPB scores before and after intervention
