The GS BSB premix does 2 reps for all of the 3 reps ones. And 1 for the 2 reps.
With C&T - again it's 2 reps for every 3. The push ups - it's every other set - instead of 16,14,12,10... it's 16,12,8...
The SuperSet one I did yesterday I loved it. It's two chest alternating with 2 triceps. You do the push ups, but only from 8 down.
