Mistress Laura Gets Metabolic

Today I decided to give the Rachel Cosgrove Get Metabolic workout a try. Didn't feel like working out for an hour, though, so I did a modified version. I performed only one set of each exercise, but cut my rest periods between supersets down to only 30 seconds so my ratio of work to recovery was 4:1, which seemed appropriate given the intensity level of the work periods and the fact that I was only planning to work for 20 minutes or so.

I think I want to add on a couple more circuits to create a 30 minute no-repeat workout. Doesn't that seem like a dreadful idea? I'll let you know what I come up with :)
