WOW, this thread got pretty interesting, fast.
There have been a lot of good points already, so there’s not much more I can add.
I did notice that 3 1/2 years ago (I know, I brought up the “3 years ago” thing a lot already, but it’s been a while) I was doing what many would consider too much cardio for gaining mass.
I was working out for 45min, 3 days a week, on an empty stomach. I was going at a fast pace (hr 170-175) for the majority of the 45min. At that time I was the leanest I’ve ever been, around 8%bf (24%bf is the worst I’ve been and I’d say I’m around 17% now).
I was also at my strongest lb for lb at 148lbs, benching 335, deadlifting 425 and squatting 415 with just a belt and wrist wraps. As far as mass was concerned, well, I was 148lbs. I had much less muscle than I do now.
I’m now trying to find a happy medium (geared more for mass) by doing heavy compound movements, with some direct muscle work, and I’ve cleaned up my diet considerable (as recommended by Professor X) and have been doing my GPP or jogging on a treadmill (as Nate Dogg has reminded me).
There is a reason that the strength coaches add in some sort of ESW, depending on how much your workout is going to affect your CNS. CW says to add GPP or slow to moderate cardio for 20-30 min for a lot of his routines on off days, and CT described the benefits that short interval sprints can have, even when the goal is to gain muscle.
Going back to Tom Venuto’s writings, he seems to favor cardio more than most, but he also takes each individual’s body into consideration. He recognizes that some may need very little to no ‘cardio’, and others may require cardio 6-7 days a week (but that’s in his fat loss articles).
I guess the point is to see what works best for your goals in your body. If you’re gaining muscle, but are gaining more fat than you’d like, you can try adding in some type of ESW and see how your body reacts. If you notice that you’re not gaining muscle as fast, then you can reduce the amount or change the type of ESW, and also look at your eating and training routine.
Sorry for the long winded post…
