Method of exercising biceps brachii
First, the vertical barbell bends.
Stand up straight, hold the bar in the middle (shoulder width) and hang the barbell in front of you. Keep your upper arm close to your sides, bend upward, and focus on the whole biceps brachii until the biceps brachii is completely tightened, and then stop for a period of time.

Then slowly control the reduction so that your elbow can be fully extended. If you bend your arm, it is difficult to stimulate the lower end of biceps brachii embedded in elbow bend. The standard frequency group should deliberately straighten the arm; However, after 8 times or less (heavy load), in order to prevent unnecessary injuries to elbow joints and tendons, it is necessary to maintain the natural flexion and extension of arms.
