I've done all of them now and am really impressed. They are all of varying intensity, but none are low intensity. Some are super intense, others just intense. I will probably never do just one on its own--I will always combine two or three WODs for a good workout--or tack one of them to the end of a strength workout for a cardio burst. I hate the warm up, so I will always do my own warm up.
The only WOD I did not like was Strength WOD 4. I felt it was dangerous and could cause repetitive movement injury. I was in quite a bit of pain by the end of that one and not the good pain. But other than that, I really liked the other 11 WODs, some more than others. I especially liked Cardio WOD 4--very intense for such a short WOD (only 8 minutes!); the perfect add on when you feel you really need to have some cardio on a strength day but your strength workout took most of your time.
I love short intense workouts like these for two reasons. I workout in the morning before work and I only have a limited amount of time--my workout needs to be no more than an hour. I can push it to 70 minutes but then my time to get ready for work and eat breakfast is a little tight. 70 minutes is my max in the morning. So having these short WODs to tack onto strength days is a godsend. I have some others, but not many (Insanity Fast & Furious, TurboFire's HIIT 15, Cathe's TTM and CF tabata premixes). Now with Bob's WODs and Zuzka's ZCut Cardio Power workouts I now have tons of super short HIIT workouts!
I also prefer these kinds of workouts when I am doing doubles (a second workout in the afternoon after work). I love my long workouts to be in the morning. If I am going to do doubles, I want it to be no more than 30 minutes, but it needs to be intense so it isn't a waste of my time. Again, combining two of these fits that bill. So, for my purposes, Bob's WODs are perfect.
