What resistance training method is being used when the client is performing a set of bicep curls immediately followed by triceps pushdowns?

Pyramid training involves progressively increasing or decreasing the load and/or repetitions across successive sets of the same exercise, not alternating between two exercises.

A superset involves completing one set of an exercise and immediately performing a set of a different exercise with no rest between them. Pairing bicep curls with triceps pushdowns is a classic antagonist superset, working opposing muscle groups. This technique improves training efficiency and can enhance recovery of the opposing muscle during the alternate exercise.

Plyometrics refers to explosive, stretch-shortening cycle movements such as jump squats or box jumps, which are unrelated to the described bicep curl and triceps pushdown pairing.

A split routine describes how workout sessions are organized across days by muscle group (e.g., chest day, leg day), not the structure of sets within a single session.
