Yes it works....and yes, it's hard!!!
What I like about it is that you can pace yourself. The first week, I pooped out after the first 45 mins of each workout and just laid on the floor....ha-ha!! Actually, the very first day of workout, I remember getting into the shower after completing less than 45 mins of the hour workout and thinking, "what have I gotten myself into?" But, after I pushed through the first week, I was able to keep up with the videos a little better.
I didn't notice too much loss on the scale but I noticed a lot when measuring. I lost a bunch of inches and my middle was starting to look very toned. Muscle weighs more than fat so they say your best bet is to be sure to take pics at the beginning, at 30 days, at 60 days, and upon completion....trust me... if you stick with it you WILL see the difference.
My DH and I getting ready to gear up for another round shortly.
