Like many people have pointed out, the intensity mostly depends on how you want to do it. You can cut yourself some slack and even cheat on the excercises, but you can also do them the hard way.
One thing I sort of disagree with some here is the yoga part. Sure, many of the poses are not taxing on the muscles, but I find that they require total body coordination much moreso than the aerobics or muscle excercises. It may not feel so much when you're doing them, apart from the chair pose, but you're constantly flexing your abs and back to stay in balance, and that's going to make a difference in your daily life just as much as those muscle workouts.
