Each show was 30 minutes divided into four segments, one of warmup exercises, two main exercise segments, and a stretch/cool-down segment. One instructor leads the exercises, with four demonstrators following to the side and behind. Later shows were shot outdoors at scenic locations around Sydney, in earlier shows an indoor studio was used.
