First step would be to drop the CARDIO.
Unless you are really fat, and really strong, cardio is somewhat counderproductive IMO.
Conditioning is a different thing all together though. The way the guys at westside and elitefts address conditioning is differnt than most others. Its considered GPP and work capacity. Read articles about it on both those sites, it will start to steer you in the right direction.
There isn't really a right or wrong way to do it, but there are a ton of options. Over there, they are big on pulling the sled, and "extra workouts" Its something that takes time to build, but the whole point is to allow you to train harder, more frequently, and recover faster.
Look into the article "EDUCATION OF A POWERLIFTER" The guy in the story wanted to lift with the "big boys" but they had him pulling the sled, doing pushups, and ab work everyday. This was to get him in shape to lift. GPP.
Another thing to think about, is that STRENGTH is a major component of conditioning. If you aren't strong, there is really no way you can demonstrate a high level of conditioning. Sure you can run around all crazy like a rabbit (think soccer) or you can be very strong and fit (like a strongman competitor) It kinda depends what you would consider is a greater showing of conditioning between the two. But just think about the women in a typical aerobic class bouncing around for 45 minutes. This may be considered high intensity to them, and the may consider themselves fit since they can handle it, but for most of us this cardio is just useless.
So make your conditioning match your goals.
A good way to condition for a powerlifter, and maybe a bodybuilder is this. You'll often hear that you should try to complete your workout in 45 minutes or less. But as a beginner, sometimes this is very tough, even with just a few exercises and a few sets, because you get winded from things. A highly conditioned lifter is able to fit more exercises, more sets in the same amount of time or less. This is the aim for conditioning.
Just make sure you dont turn your weightlifting into conditioning. A highly conditoined lifter can go from set to set, exercise to exercise with minimal rest, and little strength drop off, but if you were to try, it would be likely your strength would go to shit, and the workout would be counterproductive.
