The online exercise sessions will be delivered via Zoom, led by 2 certified exercise trainers. The program will span 12 weeks, with 2 sessions per week. Each session will be 60 min in duration and will include: warm-up (breathing exercise and joint mobility, 5 min); circuit-style training encompassing aerobic, balance, and resistance training (45-50 min), and cool-down. Individual progressions will be titrated based on abilities. Exercise intensity will be monitored using the 10-point Borg Rating of Perceived Exertion (RPE) scale. To provide some form of flexibility within this study, participants who would like to occasionally attend some of their sessions in-person will have option to informing the trainers 48 hours in advance to arrange an in-person session.

Participants in the control arm will receive no intervention.

The 12- week intervention entails 2x weekly synchronous exercise sessions, delivered via Zoom and facilitated by two certified exercise trainers. Each session is 60 min in duration and includes multimodal exercises.

Feasibility of the intervention will be measured using attendance rate (attending ≥50% of sessions), adherence rate (adhering to ≥50% of the prescribed exercises), retention rate (≥50%), and outcome capture (≥80%).

Acceptability will be assessed using the CSQ-8 tool that assesses satisfactory level about the program. It contains 8 items, each item is scored from 1 to 4. Higher scores indicate greater satisfaction. There will also be open-ended questions to share feedback as well as recommendations for improvement for further participants, their perceived benefits about the program regarding quality of life and general well-being, and likelihood to recommend it to other cancer survivors. The optional exit interview with provide participants with opportunity to share in more depth about their experiences, and

Cardiovascular endurance will be assessed using the 2-min Step Test, a validated measure of cardiovascular endurance. For online assessment, participants will be instructed to stand perpendicular to the camera (i.e., with their side and either the left or right leg facing the camera); the number of steps completed by the leg facing the camera during the 2-minute test will be recorded.

Health-related quality of life will be measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). The EORTC QLQ-C30 is a 30-item questionnaire that generates scores transformed to a 0-100 scale for functional domains, symptom domains, and global health status/quality of life. Higher scores on the functional and global health status/quality of life scales indicate better functioning and quality of life, whereas higher scores on the symptom scales indicate greater symptom burden and worse outcomes.
