i think it is fun and tough. the cardio segments aren't very long so using an 8" step will keep the intensity higher. my favorite section is when you do power lunges for cardio and then two sets of leg presses back to back. }(
i just did this video tonight for the first time, but i can already feel the muscle soreness settling in. i should feel nice and sore tomorrow.
i would compare this one to bootcamp, but the weights are harder imo - esp. for the legs. i like the premixes, too. i may try out the leg/cardio only sometime when i'm brave enough. :7
