Query: Wonderful!!

I just started this workout today. I have been doing Jillian Michael's Ripped in 30 and frequently find myself very sore the next day- yet still push through the pain. I have always been a fan of Denise Austin, she's sweet, encouraging and doesnt yell that "she wants to bounce a quarter off your butt" (which you would hear frequently if you do ripped in 30). I have several of Denise's pilates and yoga dvd's but this is my first cardio dvd; I am trying to find an alternative to running. I much prefer Denise over Jillian. The moves go quick, and I got lost for a moment, but I just rewinded and did it again- so I learned the move AND got more of a workout. Overall, it's a great workout!
