Stop in for a cup of coffee

I get plenty of physical activity, but very little cardio. I did just get some this morning though. Ran several wheelbarrows of firewood up through a couple inches of snow to fill the basement steps. Been burning the stove quite a bit recently.
Like Frank said, tough to do 'exercise' when I'm already going pretty much all day long. Just not at the rate needed to get the pulse up high enough usually. I think Memike has the answer with getting a few short bursts in. Definitely needs to be morning, cause at the end of the day, I got nothing left. Been trying to work something in at least a few times a week. Also want to get the dumbells out. Most of what I do does not involve heavy lifting and then go to pick something up that I never would have had a problem with and I feel like a weakling.
I'm slowly getting weaker. Things I have moved or stored are difficult to move. I know I put it there, but now it heavy!! I walk about 5 miles a day, I have a fit bit tracker.....but still.....
