I just got my new full-sized step delivered yesterday from The Step Company. I've been using a small step I bought from Target about 4 years ago. I didn't realize how small it was until I tried the new step last night while doing Step Fit. This is the Cathe video I know the best since I've been doing it for about 3 months (I'm new). That new step made an ENORMOUS difference in my workout. I just wanted to quit in the middle because I was so exhausted. You need a lot more energy to get over that step. Another plus was that it was much easier doing flying angels and other moves on this step. I feel like I lost 5 pounds last night! Definitely worth the extra money! Whew, I'm sore.
