Stand up and grab the EZ bar with your palms up at no more than shoulder-width apart. This is your starting position.
Lift the barbell up as far as the range of motion comfortably allows you. Then lower the weight back down to the starting position. Keep tension in your arms by not completely extending them straight at the bottom. Finally, repeat the entire movement for the desired or prescribed number of repetitions.
Perform this exercise in a smooth and fluid motion
Don't extended your arms completely on the downward portion of the movement
SPECIAL NOTES & LEVEL of DIFFICULTY VARIATIONS
To increase the level of difficulty, slow down the movement or increase the weight.
This is the exercise for those that are pressed for time and want to hit two muscle groups at the same time. This movement is great for working you lower biceps and your forearms. It's important to note that you need to have a strong grip to perform this exercise. If you don't and feel that the bar is slipping out of your grasp, don't give up. Keep doing this exercise with lighter weights at first and as your gripping strength increases you will be able to load the barbell heavier.
Also, make sure you get into a wide enough stance for optimum balance. A little more than shoulder-width apart is best. Finally, as you do this exercise keep your chin and head up as if looking into the horizon.
