Cluster Sets:
Are smaller sets built in a larger set with rest intervals that range from 10/15 up to 30 seconds. When you think of a set, you think of doing one rep immediately after another until you complete all of the reps.
Look like this – Do 2 reps, rest 15 seconds, do 2 reps, rest 15 seconds, do 2 reps. That, entire sequence, is one set.
Breaking that set up into 3 clusters of 2 reps allows you to use closer to 90% of your 1RM for the same amount of overall volume.
