Doing so is a big mistake in my opinion because you Anabol 5 Muscle Review simply can't build big arms without building the rest of your body at the same time. Besides, why anyone would want 18 inch arms on a set of skinny legs is beyond me. You should strive to build a balanced physique that is both big and strong throughout the entire body. Now, if you accept that you need to build muscle throughout the entire body, and not just your arms. And if you accept that to even attempt to build your arms without striving to build your legs and upper back at the same time is a waste of time, then let's see if we can make it clear how you should train to do just that.
Here's a simple plan for you: Focus on the basic exercises, the ones that involve the biggest muscles in the body. Focus on getting stronger in your squats, benches, chins, and deadlifts. Get your poundage way up before you even consider the idea of doing a set of concentration curls. By focusing on getting stronger in the major lifts, you will literally force your arms to grow even without training them directly with lighter isolation exercises. If you can't lift reasonable heavy weights in the basic exercises, you are wasting your time training your arms. Build a strong foundation in your legs and back first - you won't be disappointed.
Most trainees focus on the smaller, easier exercises well before they are ready for them. Training with the lighter exercises will not produce enough growth stimulation to build a bigger physique no matter how many sets of them you perform in any given workout. Don't be fooled by using a program that doesn't involve a healthy dose of the big "growing" exercises. These growing exercises are responsible for more muscle gains than all the other exercises combined. You simply won't gain muscle as fast as you could without them, and if you don't include them in your own routine, you might not make muscle gains at all.
