Today I was quite impressed with my endurance during my work out. A few months ago, I couldn't even walk up a flight of stairs without losing my breath.

Sound like you're making a lot of progress!

I sure have, but it's such hard work. I make sure to work out, even on the days that I don't want to. It's definitely taken a lot of will power.

That's great! All the hard work is paying off.
