60/40 in 30

I joined a gym. At 61 I joined a gym for the first time.

My goal is to do 60 reps on each machine with 40 aerobic stair steps between each machine done in 30 minutes.

The trainer said a person burns over 800 calories when sustaining the circuit workout at 60/40 in 30 minutes. A vigorous 30 minutes on an elliptical machine burns just over 300 calories, according to the Internet.

I've started at 20/15 in 30. When I reach the goal performance, we'll just add more weight to each machine. Is there no end?

I'd love to hear your stories, advice or tips on getting the most out of a gym membership.
