The program promoted reflection/introspection of physical activity behavior

	The program provided valuable suggestions to progress from a focus on the injury to resuming normal daily activities	“It definitely gets you from being focused on the actual injury to getting back into life, getting that groove back into life.” [Participant 001]
The program improves social cognitions related to physical activity participation
	The program enhanced participants’ intentions to plan and schedule physical activity.	“It was very valuable because, like I said, I'm going to apply this to my everyday life from now on, and I'm going to start setting more planned goals and put them into motion.” [Participant 009]
	Goal setting and vicarious experiences were memorable techniques that were learned from the program	“I think the positive is kinda relaying how you would go about obtaining a goal, like the time aspect of it. Set it 10 minutes per day, 30 days. And, the stories about the spinal cord injuries. Just seeing somebody else overcome the journey you've already been on.” [Participant 005]
Positive perceptions of the quality of the program
	The content provided information that was meaningful and relevant to the individual	“It's really a new day about spinal cord injury, and it show a lot about peer support when you're a spinal cord injury. It shows a lot about activities, it shows about people who've had trauma in their life and who have overcome the trauma, and they're living a very high functional life.” [Participant 002]
	Participants were satisfied with the program design	“That was awesome and I liked the way he told his story about what happened to him. Some of the drawings and the way they did, I thought that was pretty good. The animation, the way they did that. I thought that was good.” [Participant 013]

Positive perceptions of program operation and effectiveness
	The program was self-explanatory and intuitive	“It kind of explained what it wanted you to do. You just clicked on it and it told you.” [Participant 011]
	The program was easy to operate	“I guess with the mouse, with the clicking...The mouse helped me navigate through it easier and stuff, instead of using the pad.” [Participant 001]
	The program was engaging	“It's quite interactive, and well thought out I will say. It's easy to navigate and keeps you into it. So, it's very much needed for a lot of people to get back into feeling the need for this type of program.” [Participant 009]
Recommendations for improvement
	Improve visual cues/prompts to assist navigation	“The navigation was not bad, but it’s just...do I click on the box or do I move it? So that was a little confusing.” [Participant 001]
	Enhance the definition of the different types of exercise intensities and the action prompts	“The only negative I had was the calculation of the mild to moderate when it changed it from. I entered 30 and it went to 90. It's just a little confusing...Yeah. A different color on the words mild, moderate, heavy. Maybe put them in bold. A different font. Just something to make it stand out so that it's emphasized...Potentially lead with: “You're going to be asked about three different levels of exercise,“ so that you know ahead of time that you'll be asked the same thing three times just differentiating mild, moderate, and heavy.” [Participant 008]
	Provide the ability to go back to a previous screen	“Well not being able to go back to the previous screen if I messed up. I even tried to click next one time and it didn't work either. So that was a negative.” [Participant 006]
