Ttbar,
If you're looking to get lean and ripped and not interested in muscle mass you might want to try Insanity by Shawn T. It is a cardio based workout for two months, 6 days a week and I can tell you it WORKS. I did it earlier this year, dropped 25 pounds (205 to 180) 5 inches off my waist (size 32" pants now) and you will feel energized. You do need to follow a diet to make it work. If you do it, make sure you take before pics and after pics to get the FREE T-shirt, like I did.
I also did the P90X routine...not as cardio based and intense as Insanity but a great workout with free weights (or bands) as well. I alternate between the two programs now during the week. URL for both programs:

I'm 59 years old, and if I can do it, you can, too. It takes commitment, but it is WORTH IT. It might be a little tough if you have knee problems but you can skip that portion. I have not felt this good since I was 25 years old. PM me if you want more details.
And I want to thank Nina Moretti for telling me about this exercise program.
