Leg Extensions Kicked My Ass!

Yesterday was lower-body day. I was feeling good, so I took the weight up on my back squats. The last set were rough, especially combined with jump squats. I was a little fatigued after that, as I walked upstairs to do the last round of leg extensions.
That was rough, let me tell you. My ego told me that I didn't need to take the weight down. My practice quickly told me otherwise. I had a total breakdown of form, so I stopped, took the weight down, and then started over. I got through two more sets, with the elegance of my form just beginning to break down right at the end.
The calf raises afterwards were a relative breeze, though. And it was another excellent, much-needed break from a long day at work.
