Last night I did weights but not additional cardio on the elliptical, and I felt better afterwards. I think I was trying to do too much. While lifting, I did get cardio effect, so hopefully that was enough. Since I wasn't doing cardio, and I was able to get at a couple of barbell stations, in addition to a couple of upper body machines I did squats and deadlifts, and lower weights but 3/15 reps. There was definite cardio effect - I saw my cheeks got pink for a few seconds, and my heart pounded.
I was still tired when I got home, but not in the same draggy brainless way. By which I mean the nonfiction book I was reading made my mind wander, but not because I was tired. My mind wandered because the book was kind of boring.
In more exciting book news, I recently ordered a couple more Osprey books on WWI, and the Canadian Corps one has arrived. It was cool to flip through that after having recently read a memoir by a member of the Canadian Expeditionary Force. I saw pics of the Ross rifle he complained about.
