I don't often write reviews of products, but since this workout video is so new I thought I would give my perspective to those who are thinking about purchasing it. I did the entire video yesterday (a 5 minute warm-up, a 15 minute circuit with Anna, a 15 minute circuit with Bob, a 15 minute circuit with Dolvett, and a 5 minute cooldown). While I did feel like I got a good workout, there were a few things that frustrated me.
Anna is not a good fit for an instructor in a workout video. She may be able to get you to work up a sweat, but I found myself more annoyed as time went on during her circuit. She doesn't count and it's VERY difficult to tell when you are going to transition into the next move. She make peppy little comments to the others doing the moves (the heavier versions of some of the contestants on this season's Biggest Loser), but it comes across as very fake. The workout itself is choppy and difficult to follow. You do work up a good sweat, but if you're expecting a professional, smooth workout, then Anna's circuit is NOT for you.
Bob's workout was by far THE BEST on this DVD. It was classic Bob. Very focused on form and giving you a heads-up when you were going to switch to something else. I enjoyed his circuit the most because it was what I have come to expect from a Bob Harper workout. A nice, challenging, calorie burning circuit.
I love Dolvett on the BL show, but I was also slightly annoyed by his circuit (but for different reasons). His 15 minutes consist of something called "Tabata" which means you do one exercise for 20 seconds and then rest for 10 seconds, then do another exercise for 20 seconds and recover for 10 seconds (and so on and so on). Every time he said "Tabata" I heard "cibatta" (who knows, maybe I was hungry) and I wasn't thrilled with the choices of exercises he gives you to do during the circuit. There were a LOT of lunge and squat-type moves which are hard for people with bad knees. The modifiers for those moves don't really produce as much effort so I'm not sure you get the same amount of burn as if you do the full exercise (and in my case, possibly mess up your knees).
The warm-up and cooldown portions of the DVD were nothing outstanding, but I think they were well done. Again, my biggest complaint with this DVD was Anna and her lack of communication during her circuit. Knowing when to stop an exercise and when you are switching to something else is very important to me in an at home workout. I didn't get that from her.
Overall, you do work up a pretty good sweat and I'm sure I burned some calories (although probably not as many as I do in a solitary Jillian Michaels or Bob Harper DVD). The whole Calorie Knockout workout does go by pretty quickly, though, which is always a bonus. I'll try this DVD a few more times before deciding whether or not I want to trade it in or keep it in the rotation.
