This is the best workout I have ever had! It works your entire body and is never boring. I have been going for a little over 4 months and we have never repeated the same workout. If you are determined to get in shape, and you want to be motivated to succeed then take up kettlebells at Synergy Kettlebell. I have seen great results in a relatively short time and so have a lot of the other members. Try it out and see if you can handle the challenge, too! -Carol L.
