A1) Front squat
Sets: 8
Reps: 4-6
Rest: 120 seconds
A2) Romanian deadlift
Sets: 8
Reps: 4-6
Rest: 120 seconds
Since both exercises are “A” this means I perform them in a superset fashion, but why is there a rest interval for both? I assume I do a set of the squats, wait 120 seconds, set of deads, wait 120 seconds and repeat?
A1) and A2) doesn’t always designate a strict superset where you have no rest between the exercises. It just indicates that you perform them in an alternating fashion.
So, yeah, you have it right: perform a set of front squats, rest for the 120 seconds; perform a set of Romanian deadlifts, rest 120 seconds, and so on.
