Unless your trying to lean way out and train for endurance then I would take your cardio to the weights. You might very well loose muscle mass with cardio before, a workout. I know this goes against alot of magizines but hey whoever said the world was flat, you make the call.
Here's what works best for me.
You will have to change up your workout quite a bit but it will be worth it. Say on a particular cardio day choose chest, bicepts, and traps. Hit a set on one muscle, then without resting jump to another muscle, then the third. This should be around 3-5 minutes rest (for that muscle, not you) untill back on the first muscle. The key is to get your heartrate up while lifting. This has nothing to do with high reps, low heavy will jack your heart also. Don't go crazy with it to the point of lacking proper oxygen and you'll find you can still pull heavy weight from switching bettween muscle groups. Where you set your level and heartrate is up to you and your endurance. Cardio for cutting is really no more than accelerating your heart to burn excess fat. Why waste all your limited, precious, hormones on riding a bicycle, walking stairmasters, running, ect? A drink bettween won't restore that.
What this does is kill 2 birds with one stone. You can cut your time and not loose as much muscle mass. Look up some scientific studies of stimulating a muscle for a long period of time and see if it doesn't loose mass. Take in protein and a few carbs before and after your workout.
Hope this helps!
