Here's what I've been thinking about:
As you gain and loose weight, you tend to gain and loose fat and muscle in a ratio similar to your current body composition.
So, if you're fat and you lose a pound, that pound of weight loss has a
high fat to muscle ratio.
If you're lean and you lose a pound, that pound of loss has a
low fat to muscle ratio.
Gaining is similar.
If you're fat and you gain a pound, that pound of gain has a
high fat to muscle ratio
If you're lean and you gain a pound, that pound of gain has a
low fat to muscle ratio.
Correct me if I'm wrong on this, but I have read this many times.
So how on earth can someone gain a very muscular physique?
Bulking and cutting
should be an exercise in futility. What is the
difference?
Outside of drugs, I have to say the exercise is the
difference. Yes, there may be some nutrient partitioning characteristics of certain foods, but I would tend to beleive that plays a very, very minor role.
Exercise has to be the key. Take to fat guys who diet, one with exercise, one without. Studies (see EXRX) have shown that in obese and overweight subjects, the guy (or gal as in the studies)
will lose weight, yet gain muscle -- the newbie phenomenon. The other guy (or gal) will lose weight, but will lose both fat and muscle.
Now I don't have a study to refer to, but suppose two elite body builders at say 8% BF, go on a 6 month binge. One continues to exercise, the other becomes a couch potato. Yes, they will both gain weight. My instinct is that the first one will gain fat and muscle. The other will gain fat, and probable
lose muscle, due to the cessation of the elite level of training.
Now, I've used the word "exercise" pretty loosely. In my book, there is resistance training and cardio (I'm not considering any other varieties, hybrids, unusual training forms, etc.)
In general purposes:
Cardio is for losing weight
Resistance is for gaining weight
But doing cardio while bulking, and resistance training while cutting,
i.e. reversing the general purpose of each form, makes the
difference that I asked about earlier, correct?
You lift when you cut to minimize muscle loss. You do cardio when you bulk to minimize fat gain. That is what prevents the cutting/bulking pattern from being an exercise in futility.
Now, when do you do cardio, when do you eat, how do you lift ... and on and on ... these are what we need difinitive answers to in order to optimize the muscle gain and fat loss we all want.
I believe that HST is the answer to one of those question ... how to lift.
I don't know about the rest.
I have strong feelings about HIIT cardio. The fact that it turns up the metabolism to such a degree, burning fat while not exercising, leads me to beleive it is muscle sparing, and should be done while cutting. Others say the intensity leads to imediate muscle burning. I'd like to see a study on HIIT on fit people, instead of overweight women...
OK, I'm just about out of gas on this. Hope I've done more than just state the obvious. I bet someone will let me know what they think!
