What is the difference between EZ bar curls and straight bar curls?

The EZ bar features angled grips that place your wrists in a semi-supinated position, reducing wrist and forearm strain compared to the fully supinated grip of a straight bar. This makes the EZ bar more comfortable for many lifters, though the straight bar may provide slightly greater biceps activation due to the fully supinated hand position.

Where should I grip the EZ bar for biceps curls?

Grip the inner angled sections of the bar with your hands positioned slightly narrower than shoulder width. This grip angle provides the best balance between wrist comfort and biceps engagement for most people.

Should I fully extend my arms at the bottom of EZ bar curls?

Yes, you should fully extend your arms at the bottom to maximize range of motion and ensure complete biceps development. Stopping short of full extension reduces the stretch on the muscle and limits the effectiveness of each repetition.

Biceps Curl (EZ Bar)

The biceps curl with an EZ bar is a variation of the standard barbell curl that uses an angled bar to reduce strain on the wrists and forearms. It targets the biceps brachii while allowing a more natural grip position throughout the curling motion.

Muscle group: Biceps
Primary muscles: biceps
Equipment: Barbell

How to do the Biceps Curl (EZ Bar)

Stand upright holding the EZ bar with an underhand grip on the angled sections, arms fully extended and elbows close to your torso.
Keep your upper arms stationary and curl the bar upward by contracting your biceps until the bar reaches shoulder height.
Pause briefly at the top of the movement while squeezing your biceps.
Lower the bar back to the starting position under control, fully extending your arms.
Repeat for the desired number of repetitions without using momentum.

Form tips

Keep your elbows pinned to your sides throughout the entire movement to isolate the biceps and prevent shoulder involvement.
Avoid leaning back or swinging your torso, which shifts tension away from the biceps and can strain your lower back.
Control the eccentric portion by taking two to three seconds to lower the bar rather than letting it drop quickly.

Common mistakes

Moving the elbows forward during the curl reduces biceps tension and turns the exercise into a front raise hybrid.
Using excessive weight forces you to swing the bar up with momentum rather than lifting with controlled biceps contraction.
Stopping short of full arm extension at the bottom cuts the range of motion and limits muscle development.

Sets and reps

For hypertrophy, perform 3 to 4 sets of 8 to 12 reps with moderate weight, while strength work typically uses 3 to 5 sets of 4 to 6 reps with heavier loads.
