Stand holding an EZ-curl bar using a shoulder-width supinated grip (palms facing upward). Your elbows should be almost fully extended, and the bar should be resting against your thighs.
Keeping your upper arms fixed by your sides, exhale as you curl the EZ-curl bar up toward your shoulders.
At the top of the movement, hold for a count of two and squeeze your biceps.
Inhale as you lower the EZ-curl bar to the starting position in a controlled manner.
Comments and tips
Keep your elbows by your sides. Only your forearms should move.
Keep your body still. Do not sway your body or swing the EZ-curl bar.
Compared with the barbell curl, the EZ bar curl reduces the pressure on your wrists. However, the camber (bend) of the EZ-curl bar must be minimal. The steeper the camber, the less emphasis you will place on your biceps brachii and the more emphasis you will place on your brachioradialis instead. Therefore, if a straight barbell doesn’t feel hard on your wrists, you can use that instead.
Your biceps brachii has a short (inner) head and a long (outer) head. The long head makes up the majority of the peak of your biceps, while the short head sits on the inner side. Using a regular (shoulder-width) grip when performing the EZ bar curl or barbell curl will place approximately equal emphasis on both heads. Using a narrow grip will emphasize the long head and build the peak of your biceps. Using a wide grip will emphasize the short head and give your biceps more width.
