re: Thoughts on supersets for the same body part?

The program I just started is exactly this. Upper body workout the other day was shoulders, back, arms, chest in that order. Shoulders was narrow grip OH press, front raises, then wide grip OH press. As many reps in 30 seconds for each movement. Rest a minute and repeat. Back was bent rows, reverse fly, wide grip bent rows. Arms was standing curls, triceps kickback, then cross body curls. Chest was narrow grip DB press, wide grip DB press, then push-ups. I subbed out DB flies in place of push-ups. Takes about 20 minutes and you just go through each rotation twice.
