Hi Chevyman,

You can do it that way and you may see a benefit if you're doing more intensity since you keep burning calories after the exercise is over. It's a good idea especially if your knees hurt. That's why on the treadmill I do more incline than speed since I don't want to pound on my knees too hard or they start to hurt. At the gym, I find it helpful to switch from elliptical to treadmill because I found I can do each one better for short periods of time than one long session on either so I do 15 min elliptical, 16 min treadmill, 15 min elliptical, 16 min treadmill and 10 bike (I don't like doing the bike but I figure it's another way to move your legs so I do it for 2 miles) If I do weight training also, I throw in the weight machines in between the cardio for even more diversity.

I actually was reading on another site the very question you just asked in a FAQ and they also answered that it's fine to do it that way. They also said if you do over 60 min of cardio, you don't get much more benefit since after 60 you start getting diminishing returns for your effort.
