I've done the "No Repeats" premixes and MishMosh#1 premixes. MishMosh #2 is for next week.
The "No Repeats" means there is only 1 set of each exercise, however, when there is a difference in the sets - as in Legs - Squats - 3 sets are done (1 regular (instead of 2 sets), 1 w/Fabric Loop, 1 w/plates); also for the Elevated Lunges both sets are done as there is the upright set and the forward-leaning set. But for things like Hip Thrusts - you do just one set. You can see the actual breakdown in the User Guide or on the Workout Manager.
For the No Repeats for Chest/Tri's and Back/Bi's I actually added in additional sets to get a more "worked-out" feeling. I didn't for the first No Repeat of Legs/Shoulders because I didn't think of doing so - but wished I had - it doesn't add on that much more time to do a few more sets of the exercises you think you'd benefit most from. That way you get a shortened workout and a more "worked" feel. If I had thought of it, I would have added in additional sets of Hip Thrusts - seemed hardly worth the effort to do only one set.
For MishMosh#1, I added in the Bonuses of both body parts to lengthen the workout.
