I have more than one biggest loser workout. I LOVE THEM. I like them because you start out with a 30 minute workout and add onto it from there. I like this one because my love handles are always sore after I do it. :)
I also love any Jillian workout. I like this one because it isn't straight cardio. She does circuits: 3 minutes of strength, 2 minutes of cardio, and 1 minute of abs. It makes it do-able. You also start out easier and work your way up to the hard ones. If you are like my sister Suzy you do all three levels at once holding 15 pound weights in your hand for the whole thing.... but I haven't quite reached that fitness level yet. I also like this DVD because it is 30 minutes for each workout. Great for when you don't have a lot of time.
Ellen Barret... love her too. She does pilates inspired workouts. All of her DVDs in "The Studio Series" I love. I like variety and her workouts are not as high intensity as the Bob Harper or Jillian Michaels. I like Skinny Sculpt because you are holding light weights for most of the workout so it is a great workout for your arms. Just when you think you can't hold the weights any longer, you switch to abs. She also stretches you very well and I love how you feel at the end of it.
Even after putting these three down I can still think of a lot more I would never give up. :) Good thing I will never have to. What are your favorite workout DVDs? I am always on the look out for more. Enjoy your work out!
