My question is my biceps are great and my triceps are”meh”. I’ve normally been doing 9 sets for biceps and 9 for triceps. Is this too much volume? I never feel over trained because I can’t do deadlifts or squats. Am i shooting myself in the foot for doing too much volume to force tricep growth? I do close grip bench press, skull crushers, seated dip machine, & tricep pushdowns. All of them burn! Mind muscle control is perfect. I am starting a lean bulk. It’s been about 6 months from last bulk so that might be why my triceps are still weak looking. Thoughts!? Thanks beast!
Rather than stimulating your body, niacin is able to unlock the energy that is available within the calories you consume. This means your body is able to achieve sustainable energy without any crash. While taking niacin pre workout supplements, niacin may also lead to flushing sensation which causes the skin tingle. When you realize this, known that this is normal and the effects will disappear after a few minutes. Just don’t worry if your pre-workout supplementation contains too much niacin. In fact, the more niacin, the better the results.
The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.
