Pairing opposing muscle groups, such as the chest and back or the triceps and biceps, is also very common. A good example of a chest-back superset is a flat or incline bench dumbbell press followed by a rowing exercise. A triceps-biceps superset might consist of a cable press-down and a barbell curl. Research has suggested that, because a muscle tends to receive a strength boost immediately after an intense contraction of its antagonist (a muscle that performs the opposite movement), you might actually be stronger on the exercise performed second in the superset than when performing that exercise via straight sets.
