Sometimes used by trainers to describe a workout involves cycling between two different exercises for two sets, before moving onto another two different exercises and doing the same.

For instance, as part of a workout routine person might perform:

☛ 1 set of leg raises (A)

☛ 1 set of crunches (B)

☛ 1 set of leg raises (A)

☛ 1 set of crunches (B)

before moving on to do another group of two exercises.

When employed in weight lifting, alternating between different exercises might be referred to as ‘super-setting’.
