What’s your favorite exercise video DVD workout? #getitguide

This month as a Yahoo! Shine Get It Guide Guru , I was given the task to review four different exercise video DVDs. You can read my review at You’ve gotta move it! My review of 4 fitness DVDs .

I reviewed these exercise video DVD workouts:

• Kettlebell workout DVD with Bob Harper – my favorite exercise video DVD. Note: this is the GoFit DVD and kettleball set you can buy at Target. It's not the video available at Amazon.
• Jackie Werner Crunch-Free Xtreme Abs – This was my second favorite exercise workout video as it really worked my core. It could have used a better warm up and cool down though.
• Zumba Fitness Total Body Transformation System – I didn't care for this exercise video DVD set as I’m not much into dancing and Latin music. But if you are, then go for it. It's a nice set for the money.
• INSANITY Fast & Furious: 20 Minute Maximum Fitness Results Workout – This exercise workout video was way too advanced for me. Even the other Get It Guide Gurus thought it kicked their butts and thought it was too strenuous.
