How to Get Big Arms
To sculpt bigger, stronger biceps and triceps, it helps to arm yourself with a bit of knowledge about your muscles and how they work. Your upper arms are divided into three main muscle groups. Firstly, we have the biceps, which run along the front of the arm from your elbow to your shoulder joint. The main function of the biceps is to bend the elbow. Secondly, we have the triceps that also run from the elbow to the shoulder, but their main role is to straighten the elbow. The triceps are a larger muscle group than the biceps, which means they have more potential to grow. The third group is the brachialis, an upper arm muscle that runs under the biceps. It's really only visible when looking at the arms from the side, but will make your arms appear much larger when viewed this way. Although most people focus on biceps training, if you want really big arms then you need to work your triceps and brachialis just as hard. To get a truly sleeve-busting look, you need to work the triceps, biceps and the brachialis.
