I see posts very frequently by guys that are just completely CLUELESS about the role genetics play in how one responds to training. These posts USUALLY come from one of two types of people. Guys with great genetics that have never had training partners that didn't, or have never worked with a group of lifters over the long-term, and young guys that REALLY, REALLY want to believe that they can be the next Arnold, Yates, or Coleman.

Here are just SOME of the factors that ultimately determine how big and strong you get, and what paths are appropriate to get you there:

Insulin output
insulin sensitivity
Thyroid output
Thyroid sensitivity
Testosterone production
Testosterone/hormone sensitivity
Testosterone to estrogen conversion
SHGB sensitivity
Testosterone to DHT conversion
Estrogen sensitivity
Growth Hormone output
Growth Hormone sensitivity
IGF output
IGF sensitivity
Digestive capability
Basic protein synthesis ability
Muscle fiber composition

ALL THESE FACTORS ARE ALL DETERMINED BY AN INDIVIUALS GENETICS. AND THEY DON'T VARY A LITTLE, THEY VARY A LOT. AND THERE ARE MANY, MANY MORE!

Take a guy that has very little fast twitch fibers, or just very little muscle fibers compared to the average person, or well above average person and this person is NEVER, NEVER going to have anywhere NEAR the growth potential of someone that has more fiber to begin with no matter HOW BIG they hypertrophy them.

Oh, just add steroids and the below average guy is even. WRONG again. In the Soviet Union where the state spent much time researching these issues, they determined that hormone (steroid) sensitivity varied as much as 2 to 4 times. Which means the response and thus results one guy might get from a gram of gear would take 4 grams for another person to achieve. And these were highly technical studies carried out with good controls. Not what a bunch of gym meatheads observed. YES, THAT IS genetics in action.

To say genetics only accounts for a small degree of the achieved results is just PLAIN FLAT OUT WRONG AND ANY GOOD STRENGTH COACH OR SPORTS PHYSIOLIGIST WILL TELL YOU THAT.

This does NOT mean you cannot make great progress or build a great body, but it does mean that most just simply don't have the potential to be top bodybuilders. And EVERYONE responds differently. I am not trying to rain on anyone's parade, and potential can only be known in retrospect AFTER you have tried. But all these posts by guys saying genetics are not important and guys just use them as an excuse is pure BS

Bumpity bump bump. I think this is important for every bodybuilder enthusiast to read or you might get disillusioned if you can't attain the physique you desire.

Take some time to understand a bit of this.

BUMP!
