My experience, being a competitive distance runner and avid weight lifter, is that I have to eat like a horse to gain (derrr). But it is very possible. My freshman year of college I gained about 15 pounds (lbm), and I was doing more mileage than in high school obviously. I was eating the school meals, which are huge in caloric value. The cool thing was that it went to all lean mass. Since then, i've been preparing my own meals more often, and not getting nearly enough calories. Since freshman year I haven't gained much. So, to sum my experience, doing endurance cardio and eating a boat of calories lead to positive partitioning.

Please all refer to the Dulloo et al work on the p-ratio; it is nothing inherent to cardio above and beyond it's metabolic demands at a given level of endogenous adiposity and external nutrient ingestion (i.e., energy balance). Once you get to a certain level, demands exceed resources and partitioning changes from one primary source to the other; Running however, will cut the hell up out of your legs...maybe not the size from going heavy and deep on leg work, but most certainly tone. Running also is a great partitioner.

I just wanted to chime in and second your statement about running cutting up the legs. Since i started regular cardio about a year ago my legs have beome a lot more cut and veiny along with a lot of at reduction on my inner thighs. Only problem is my legs are so damn hairy it is hard to see it unless they are pumped.

Not sure what you're getting at. If you're saying that - at the point that demand exceeds resources - partitioning favors BF and less LBM, that's wrong. Partitioning is not a function of one parameter. In BB there is ALWAYS strategic overload. Favorable partitioning comes first from weight training... the result of lower rep work with it's higher demands for nitrogen balance, in conjunction with rebalancing of macronutrients towards protein and fat. This resistance work IN CONJUNCTION with the endurance work mentioned together form the basis for favorable partitioning.

QUOTE Running also is a great partitioner.

Running per se is not anything. It can be tremendously catabolic.

Research 'Concurrent Training'. Lifting weights can have a positive effect on a distance/endurance athlete because it can make them more biomechanically efficient, but take a strength athlete and have them do anything endurance and you'll see decreases in strength. The same however is true with endurance; their VO2 will decrease, but at the same time they'll be stronger so it works out favorably. With a strength/power athlete, it is hypothesized that training both characteristics simultaneously results in overtraining - so then you'll have decrease in strength, power, size, etc..

If you need to look further, check out elite caliber decathletes. You'll find those who do better in strength events do not do well in the 400 and 1500, and those who do great in the 400 and 1500 do not do as well in the strength/power events. Also compare their body types to say - a sprinter. Most decathletes look more like a 400 - 800 meter runner than a 100 meter sprinter.

Inner,

Running by itself can favor partitioning simply through mitochondrial mechanisms and there are lots of papers on this; what I was referring to in the first part of my post was work by Dulloo et al., dealing with the p-ratio. Clearly running can be catabolic, but clearly it can be indirectly anabolic.

While not to sound trite, and without going into excessive detail (I don't refute anything you said as an aside) I do know what I am talking about here.
