Hour of Power (No,Just Cardio)

I actually logged 65 minutes of cardio this morning, which felt really good. I started with walking (2.13 miles in 40:07 min) on the treadmill, and followed it with 25 minutes (4.41 miles) on the recumbent bike. I didn't make time for strength training or stretching this morning like I should have, but the cardio felt sooo good. (Only bad thing was a few twinges in my left knee as I walked.)
