Reported barriers, facilitators, and benefits of My Body physical activity program

	Intrapersonal	Interpersonal	Community	Exemplar quotes
Barriers to engage inMy Bodyphysical activity program	Time management: restricted according to medical appointments	Limited social support (family, employers)	Socioeconomic status given the personal competing priorities to invest money and time	“I say, what more to do than clean the house, sweep, do laundry, go get the kids, the grandkids from school, come back…what more exercise than what I already do.”
	Limited self-efficacy: not feeling able to dance	Intrahousehold gender disparities to distribute care and home tasks	Lack of physical activity programs offered within the health care system
		Fears and risk perceptions from family and some healthcare professionals
Facilitators to engage inMy Bodyphysical activity program	Personal enjoyment through dancing	Group-based physical activity practice enhancing social support represented in program companions (friends, family)	Motivated knowledgeable staff trained to address breast cancer related issues and physical activity	“I’d think: the cancer, 20 rounds of chemo, 10 rounds of radiotherapies, how would I be able to even lift a finger? Then when I saw myself in this program I thought ‘no way, this is great’. Knowing that not everything is bad, that after all what cancer put me through, I was able to dance again”
	Positive beliefs regarding physical activity	Guided physical activity changing risk perceptions and strengthening motivation	Interdisciplinary team (sports physicians, psychologists, respiratory therapists) providing safety, respect, and affection
	The resilience process associated to the disease	Peer care network (emotional support and role modelling)	Location of the sessions was accessible by public transportation
Perceived benefits from engaging inMy Bodyphysical activity program	Increased energy (vitality) and endurance to perform daily tasks			“This program truly helps and should be growing even more. I don’t know where to go, if I should go to where I got treatment, to the chemo room and tell them ‘look, there’s a program for this, to help us with our self-esteem because it goes so low’. I’d love to spread the word because I suffered a lot and I don’t want others to go through what I went through. On the contrary, I want to walk into those chemo rooms where people are pitying themselves and tell them, ‘no, we’re going to get through this and get healthy and pretty’.”
