FATPOCALYPSE

For this method, you'll be doing 6 mini-sets of 4 reps, taking 10 seconds rest in between each mini-set. This counts as one Cluster Training set.

Have two dumbbells set on either side of the bench so you don't have to shift one dumbbell around. Go back and forth between sides with no extra rest...just the time it takes to set up for the next arm.
