Sitting on my couch after a full workday that night, I was debating between going to a friend's to catch up and drink wine or stopping over to Equinox around the corner to do an arms circuit (and OK, maybe a little bit of running too). I opted for Equinox, as it was about 40 blocks closer than the wine. The workout ended up being a one-mile warmup and an arms circuit that included triceps dips, triceps extensions, bicep curls, shoulder presses, and plank up-downs. All followed by a one-mile finisher. I hit the showers and then hit the pillow.
