Well, yesterday I did some circuit training, but I'm using the Grease The Groove training method, which means doing the same thing throughout the day.

Here's what I did for 5 complete circuits throughout the day:

Widegrip Chins: 1 set of 6-8 reps with bodyweight + 15lbs.
HandStand Pushups 1 set of 15-20 reps with bodyweight.
Hanging Knee Kicks 1 set of 10 reps.
Hanging Trunk Twists 1 set of 6-8 reps
Pushups with Feet on Bench 1 set of 10 reps
Bent Over Dumbbell Rows 1 set of 10 reps with 25lb dumbbells
Upright Row 1 set of 10 reps with 25lb dumbbells
Lateral Raise 1 set of 10 reps with 25lb dumbbells
Alternate Dumbbell Curls 1 set of 10 reps with 25lb dumbbells
Overhead One-Arm Tricep Extension 1 set of 10 reps with 25lb dumbbells
Rotator Cuff Raise 1 set of 10 reps
Standing One-Leg Calf Raise 1 set of 10 reps with 25lb dumbbell

The reasons I used the same weight in the exercises:
1. I got a body composition analysis done and my torso is great in terms of muscle, but my arms and legs need to be bigger proportionally (if my back were ok, I would do squats).
2. It was circuit training with no rest between exercises although once or twice I took a few deep breaths between exercises.

That was yesterday.
