We had a sub instead of our usual step instructor this morning and I was a total grouch for the first half of class. We started late, the class was boring, and I wasn't getting a good workout. Stupid lady. Then, halfway through the class something clicked. I was mad at myself for eating too much crap last night and felt like I needed to get my butt kicked. But the person ultimately responsible for kicking my butt was me, not the teacher. I wasn't getting a good workout because I wasn't trying. In the second half I totally kicked it up. I added jumps and impact and got my arms moving. I was sweaty and gasping in minutes. It is a good lesson for me to remember, because a lot of times on the road I end up in a class that is less than optimal.
I can always work harder and if I don't get a good workout in the end it is always my fault.
