i received it in the mail yesterday and did routine one yesterday. (they give you three routines to do)
loved it! broke a sweat but wasn't out of breath. laughed out loud at the zany things they wrote on the bottom of the screen (they write funny little things like "marc anthony does not do PUSH... he should call our customer service department etc.)
today i was sore and could feel the areas that i worked yesterday. it was good! two thumbs up!
edit: they also included 2 free resistance bands as well!
