Supersetting is one of the most powerful muscle-building techniques you can use—and that’s not conjecture but scientific fact. Just as the name suggests, supersets can produce some spectacular superhuman results—plus, they’ll give you a big psychological kick as well.
When you superset, you move from one exercise to another without taking a rest. You can superset opposing, or antagonistic, muscle groups, such as the biceps and triceps, or use two movements for the same muscle group, such as barbell curls and preacher curls.»
