Screening evaluations will be conducted on interested participants and eligibility criteria include the following: a) between the ages of 18 to 80 years of age, histologically confirmed kidney cancer (Stage I-IIIa); b) ability and willingness to effectively communicate with the study coordinator and complete all questionnaires involved in the study in English; c) able to attend the supervised PA sessions and not planning to be away for three consecutive days for the duration of the program; and d) interested in increasing their PA by at least 60 minutes of moderate PA or 30 minutes of vigorous PA. Following the screening procedure and prior to randomization, consenting participants that are deemed eligible will undergo submaximal exercise testing to ensure that they are able to exercise safely at a moderate-to-vigorous intensity. Two stages of the treadmill test must be successfully completed with acceptable heart rate and blood pressure responses before any remaining baseline tests will be conducted including a physical function test, anthropometric testing, and PA behaviour, quality of life, and determinants questionnaire.
