While I don't think this workout is actually a great one, I have found that you definitely can do a killer workout in a short period of time, depending on your fitness.
I started Crossfit a few months back, and its entirely possible to do 2-3 simple movements (thrusters + pullups for example) in a short time period (2-10 minutes) and really push yourself to complete exhaustion.
