Query: Surprisingly fun and challenging!

I bought Sweating to the Oldies because I wanted to get back in to exercising and I figured these DVDs would be pretty novice, so I thought it would be a good way to ease back in to things. I was sure that Richard would be completely unbearable and annoying, but surprisingly... these workouts are FUN! He doesn't do a lot of coaching and encouraging throughout the workout like some other workout DVDs I have tried, which I appreicate because I find that to be a very annoying characteristic of other home workout instructors. Not only did I find it to be enjoyable, but I was actually breaking a sweat! This has been a great purchase for me and will be for you, too if you are looking for a way to workout in the morning before work, but can't quite make it to the gym that early.
