Sometimes I get silly ideas. This workout was one of them. Truly, it was not that silly to combine running the stairs outside the PMAC with core exercises... until your heart rate has increased so much you can barely hold yourself up with your arms. This is workout kicked my butt!
complete every exercise for 1 minute with a 10 second break between exercises... use an interval so you do not need to look at your watch as an excuse to stop
complete two rounds of the workout... you can do anything for 20 minutes, right?
I cannot wait to do this workout again soon. Crazy? Yes. But I always feel great after completing a killer workout. If you do not have access to stairs, a hill would work just as well!
