[Jean-Paul]

In a non-circuit workout you can either do set-rest, set-rest, or you can superset a push exercise with a pull exercise, like a chest exercise followed immediately by a back exercise. For the intensity that I call for in a traditional mass-gaining workout though, I wouldn't advise doing all of the exercises as circuit. You need to do the same exercise or pair of exercises several times in a row, with a little rest in between each set.

If that doesn't make sense, let me know and I will try to explain it a different way. Good luck!
