Why does my brachialis hurt?
The brachialis muscle can be commonly injured by repetitive forceful contractions or muscular contractions with the arm in hyperextension. This is commonly seen in climbers, due to the pronation of the hand and the extended started position. Physical activity that involve a lot of pull ups, curls, and rope climbing can also initiate brachialis muscle pain. A strain to the brachialis tendon can also cause a patient to present with lacking elbow extension due to painful end-range stretching of the tendon. Due to the location of the pain, medial epicondylitis and lateral epicondylitis should also be evaluated.

How to treat a tendon in the arm?
After about a week of rest, the arm should be feeling a little better. This is when other treatments will be beneficial. This might include pulsed ultrasound , which emits vibrations to the tendon to reduce pain and swelling while promoting the healing process, and trigger-point work, or manipulation of the muscles combined with cross-friction massage to the muscle and tendon to increase movement of the arm. A trigger-point is the area of a muscle that is tight which causes pain in other areas of the body. Massaging the trigger point loosens the muscle and allows the tendon to function as intended. This will help return normal range of motion to the shoulder and elbow.
How does Eric feel?

What does it mean when your pinkie is higher than your thumb?
Btw, the pinkie being higher than the thumb is the position you are trying to achieve when supinating the hand during a dumbbell curl. The supinating movement is one of the two main functions of the biceps. When the pinkie is held higher than the thumb, the biceps receives a greater emphasis than will the brachialis and the brachioradialis...but all three still function.
How to isolate brachialis?
The best way to isolate the brachialis is with static holds. They do a greater percentage of the work on isometrics than on dynamic flexion. That said, heavy curls and heavy rows will do more for the appearance of your arms than even the most effective brachialis isolation possible.
How to use overhead pulley?
When using the overhead pulley, you want to ATTEMPT to supinate the hand slightly and curl behind your head. Elbows will naturally assume a position about forty five degrees, in both the vertical and horizontal planes. It's best to do this with a single hand...the movement isn't the same when using both hands and a bar...going behind the head.
Can you isolate the biceps?
I don't believe that these muscles can be isolated. All of these three groups function more or less when the arm is flexed. Curling with your elbow high by using an overhead pulley and cable will help...but will not ISOLATE this muscle strand. The biceps and brachioradialis will still function. You will get a vicious, almost cramping contraction if you curl this way.
Did Larry Scott think bicep height was determined more by genetics?
actually, Larry Scott said he used to think exactly what you just said, that its genetic, but then he says on his site that after he "discovered" the Scott curl, he changed his mind. He doesn't think bicep height is determined more by genetics
Who said when you're 250 pounds of ripped muscle, then start worrying about the appearance of your rear delt?
I think it was Randall Strossen that said "when you're 250 pounds of ripped muscle, then start worrying about the appearance of your rear delt." I put the brachialis in the same general category.
