The apparatus to be worked on is also duplicated. Each person competes simultaneously against the other in the number of repetitions attained in the pre-set time. Most common lay out.
Participants follow circuit round selecting own intensity of work.
Suitable if class is of a varied fitness level. Split Circuit Person moves along line of apparatus performing predetermined repetitions on each selected apparatus in personal preferential order no rest allowed. For example 15 reps on each exercise, then move onto next exercise. Second time around reps may change. Triangles or squares can be made up exercises for one muscle group or as for the normal order in circuit training.
