I figured I better do a lot of warmup sets to get the groove since I had never really tried them before. As a result, my sets went something like:
45 x 10
75 x 10
105 x 10
125 x 10, 8
The last few sets I supersetted with moderate weight leg curls. I wasn't quite sure if I had worked my legs hard enough, so I decided to tack on two sets of regular back squats:
165 x 15, 10
A couple of sets of calf raises and leg raises later and I was almost done. Sensing that I could do more, I setup my shrug bar and knocked out one light (175 x 20) set of shrug bar deadlifts.
