Moment of Bodybuilding Zen 27: Arnold’s Secret

In our Zen 3 newsletter, we talked about Arnold’s biceps peak and his full-range workout (POF: standing curls, incline curls, concentration curls).

But Arnold’s secret to eye-popping bi’s: He trained his brachialis muscles directly. Those lengthy muscles snake under the biceps and connect down on the forearm. When the brachialis are beefed up underneath, they push the biceps higher when flexed—sky-high peaks.

You can see Arnold’s brachialis muscles in the photos above—the “ball” on the outside of his upper arms between his biceps and triceps. You can also see those important muscles in this classic Jimmy Caruso studio shot…

So what is the best exercise to beef up the brachialis? In our X-traordinary Arms e-book we reveal the best exercises for all the arm muscles, including massing up that peak producer…

MRI studies show that the incline hammer curl totally lights up the brachialis better than any other move. Standing hammer curls only stimulate it moderately with more emphasis on the outer biceps head. That’s not a bad thing—as we reveal in X-Arms, it’s the head that contributes unique peak properties too. 

There’s more on which biceps and triceps exercises focus on which heads in our X-Arms e-book, along with complete routines and how to perform each exercise to turn your arms into sleeve-stretching pythons. 

By the way, that’s Jonathan’s drug-free 19-inch arm on the cover below, and he used most of the tactics in this e-book…
