I just received this DVD and have done the first workout- warmup, low-intensity, cool down. I was in the military for three years and got out just over a year ago and began to lose my svelte figure. I am very athletic and thought the forst workout would be "easy". Well, two days later I'm still sore! It was great fun, really got my heart rate up and made me sweat! Bob is soo encouraging, albeit a little cheesy. My only complaint is that the demonstrators can't stay in time with the music, Bob, or eachother, so it's easy to get distracted and mess up. Other than that they're great! I highly reccomend this to exercisers of all levels.
