Do you use the ab roller for fitness? 
I do. It's a little challenging for me right now, though. I feel awkward using it. Have you used one before?
No, I haven't. I'd do sit-up if I want to tone my ab.
Do you workout often?
I used to, but I got lazy recently. I most jog outside or on a treadmill. What kind of workout do you do?
I mostly workout at home to save money. I do 30-45 minutes of cardio, then 15-30 minutes of resistance training, and then 15 minutes of stretching.
Wow, that's awesome. Do you follow some workout videos?
I do, I watch them on my tv. I tried some fitness apps on my phone but I didn't like it as much.
I also like watching workout videos on tv because I feel like following a real instructor.
Same here! Do you have a treadmill at home?
