If those guys with better genes trained as hard and intense as me, I wouldn`t stand a chance!

During weight cutting your mind plays tricks on you.

Complex carbohydrates are always best, except, again, after a workout where you could take simple (sugar) carbohydrates to get an insulin spike. But at other times doing this is not very beneficial because insulin is a storage hormone and it's going to shunt everything into the muscle.

The single biggest mistake that most beginners make is putting 100% of their effort into the positive (concentric) part of the rep, while paying no attention to the negative (eccentric) segment

At the end of the day it's not a weight contest, it's a visual contest. And it doesn't matter what you say you weigh, if you don't look that big then you don't look that big.

Shoulder width is an absolute requirement for displaying the V taper that will make or break your physique.

All else being equal, the guy with the best genetics will have the best physique. But rarely are all things equal.
