I just completed the first week of the Lite rotation and I love this series. It reminds me of when I first became a home exerciser (1996) using The Firm, before discovering Cathe. I love that this series provides so many options. I also love that my joints are not impacted. Even though I can still do high impact exercises, I have to be honest and listen to my body. Any many times my body says no. Lite provides the muscular and cardiovascular challenge without the impact to my joints. I'm actually considering doing a full year of low impact workouts, rotating, Lite, Ice and the Low Impact Series. Lite has also been a perfect workout to get me started and motivated on these cold winter days when I don't feel like getting out of the bed. I just had to post my thoughts about this series and say thank you to Cathe. I don't know about any one else, but Cathe this is the perfect series for me. Thanks.
