Busting a Myth: There is always the debate about shaping a muscle and it can't be done. The shape of your muscle is predetermined by your genes. I call BS, because no you can not change the general shape of your muscle fibers, but you can build certain heads of a muscle to make it appear to have a different shape.
Ex. Chest- What do people complain of all the time in their chest? That the top portion is lagging, and they have a saggy chest. What's the simple solution? Start off with an incline movement first on your chest workout.
Now to biceps. What is one of the best exercises for isolating the biceps? Preacher Curl. Which head of the bicep gives the appearance of a higher peak? The outer head. What grip puts more emphasis, and work load on the outer head? Close grip. So what is the exercise to help build peak on your biceps? Close Grip Preacher Curls. Preferrably with cambered or EZ bar, because using a straight bar is a good way to mess your wrist ligaments up
Other good exercises to mention....
DB Preacher Curls with arm leaning inward
Concentration Curls with arm leaning inward
Hammer Curls
Hammer Strength Preacher Curls
Any other curling exercise where a close grip is used[/b]
With this being said, don't expect to do these exercises and have a peak like Ronnie, Arnold, or Markus Ruhl, but you will see an improvement in your bicep's peak.
