Symptom burden remains a critical concern for individuals with non-small cell lung cancer (NSCLC) following the completion of treatment. Of those, symptom clusters such as dyspnea (shortness of breath) and fatigue, contribute to physical decline, reductions in quality of life, and a higher risk of comorbidities and mortality. It has been proposed that dyspnea is a primary limiter of exercise capacity in individuals with lung cancer, resulting in exercise avoidance and an accelerated physical decline. As such, specifically designing resistance exercise programs with cluster sets, to mitigate feelings of dyspnea and fatigue may result in improved exercise tolerance, resulting in the maintenance of physical function and quality of life. The purpose of this project is to investigate the feasibility and preliminary efficacy of a hybrid-delivery of home-based cluster-set resistance exercise in individuals with NSCLC. Methods: Individuals with NSCLC (n=15), within 12-months of completion of treatment will be recruited to participate in this single arm feasibility trial. Participants will complete 8-weeks of home-based resistance training (RT) designed to target dyspnea and fatigue. The hybrid-delivery of the program will include supervised sessions in the participants home, and virtual supervision via video conferencing. The primary outcome of feasibility will be measured via recruitment rates, retention, acceptability and intervention fidelity. Exploratory outcomes (dyspnea, fatigue, quality of life, physical function and body composition) will be assessed pre- and post- intervention.
Analysis plan. Descriptive statistics (percentages and means (with standard deviations)) will be used to report on feasibility outcomes (recruitment, retention, fidelity etc.). Unless explicitly stated, means and standard deviations will be reported for assessments of exploratory outcomes at baseline and follow-up.

Recruitment
The recruitment goal of n=15 is reached
Time frame: Through study completion, an average of 1 year
Retention
If ≥75% of the sample recruited to participate return for follow up testing
Time frame: Through study completion, an average of 1 year
Intervention Fidelity
Exercise fidelity will be reported using metrics previously outlines by Fairman et al (2019). Specifically, volume load will be calculated as a function of sets x reps for each exercise and summed to give total volume for each session. We will report the proportion of volume achieved relevant to what was prescribed to give a "relative-dose intensity" (RDI) for each person. RDI will then be averaged and used to determine fidelity to the RT intervention.
Time frame: Through study completion, an average of 1 year
Acceptability
10-item scale adapted from McDonnell et al (PMID: 33118443). Questions assessing the acceptability of the intervention will be scored on a 4-point Likert-Type scale from "Strongly disagree" to "Strongly Agree". Questions will ask about the utility of virtual exercise sessions, use of technology and level of tailoring the intervention
Time frame: At post intervention (8-weeks)
Dyspnea
Functional Assessment of Chronic Illness Therapy-Dyspnea (FACIT-D) 10-Item short form (parts 1 and 2). Part 1 assesses Dyspnea and Part 2 assesses dyspnea-associated functional limitations. Min score for each part: 0; max score for each part: 30. Higher scores indicate worse dyspnea/burden
Time frame: Baseline and post intervention (8-weeks)
Fatigue
Functional Assessment of Chronic Illness Therapy-Fatigue scale 13-item scale. Min score: 0 Max score: 52 Higher scores mean higher quality of life.
