The seated EZ barbell curl is a biceps isolation exercise performed on a flat bench with an EZ bar that trains the biceps brachii through the upper half of the curl with no torso swing. Sitting means the bar rests on your thighs at the bottom, so every rep starts from a bent elbow where the biceps is already under tension and the weakest part of the range is removed, so you can load heavier than a standing curl, while the angled grip of theEZ barspares the wrists. Bodybuilders program it as a heavy accessory on arm days.
What Muscles Does the Seated EZ Barbell Curl Work?
- Primary: Biceps brachii (short and long heads)
- Secondary: Brachialis, brachioradialis
- Tertiary: Forearm flexors, anterior deltoid, rotator cuff stabilising the shoulder
How Do You Set Up for the Seated EZ Barbell Curl?
Sit on the end of a flat bench with your feet flat on the floor and your knees bent at about 90 degrees. Take the EZ bar with an underhand grip on the inner angled sections, hands a little narrower than shoulder width. Rest the bar across the top of your thighs, sit tall with your chest up and shoulder blades pulled back, and pin your elbows to the sides of your ribcage.
How Do You Perform the Seated EZ Barbell Curl?
- Set the bar on your thighs with the elbows tucked at your sides and the wrists straight.
- Curl the bar upward by bending the elbows, lifting it off your thighs in a smooth arc.
- Stop when the bar reaches shoulder height and the forearms sit just past vertical; the biceps should be fully shortened without the elbows rising.
- Squeeze for one count at the top with the knuckles pointed at the ceiling.
- Lower the bar slowly along the same arc until it is just above your thighs.
- Rest the bar lightly on your thighs, keeping tension in the biceps, then begin the next rep from the same position.
What Are the Key Form Cues?
- Curl toward your collarbones: Aim the bar at the top of your chest so the forearm arcs around a fixed elbow.
- Keep the ribs stacked over the hips: Sit tall through the whole rep so the torso stays a fixed base for the arms.
- Drive the outer edges of your palms into the angled grips to keep the wrists neutral.
- Touch the thighs at the bottom, never dump the bar onto them, so tension stays in the biceps.
- Keep the elbows pressing into your ribs as the bar rises.
What Are the Most Common Mistakes?
- Loading the bar too heavy: The bar bounces off the thighs and the shoulders shrug it up the rest of the way. Use a weight you can start from a dead stop on the thighs.
- Leaning back to start the rep: Rocking the torso turns the curl into a partial front raise and loads the lower back. Keep the chest over the hips.
- Letting the elbows drift forward and up: The front delts take over and the biceps stops shortening early. Keep the upper arms vertical.
- Bending the wrists back at the top: The bar tips and the forearm flexors lose their hold. Keep the knuckles in line with the forearm.
- Dropping the bar onto the thighs: Slamming the weight down skips the eccentric and bruises the legs. Lower with control and touch softly.
What Are the Best Seated EZ Barbell Curl Variations?
- Standing EZ bar curl: Full range from straight arms, lighter load, the version to learn first.
- Seated EZ bar partial curl: Curling only from thighs to mid-range lets you overload the top half.
- Wide grip seated EZ bar curl: Hands on the outer grips bias the short head of the biceps.
- Seated EZ bar concentration curl: One arm braced against the inner thigh isolates each biceps in turn.
- Scott bench EZ bar biceps curl: The preacher pad removes all elbow drift for a stricter curl.
How Do You Progress the Seated EZ Barbell Curl?
- Add 5 pounds to the bar once you complete all sets at 10 reps with the bar starting from a dead stop.
- Build from 6 reps to 10 per set before adding load.
- Add a fourth set when three sets no longer leave the biceps fatigued in the last reps.
- Slow the lowering to three seconds or hold the top squeeze for two counts before increasing the weight.
How Should You Program the Seated EZ Barbell Curl?
Place the seated EZ barbell curl in the middle of an arm session, after a full-range standing curl and before finishing work like cable curls. Train it one to two times per week for 3 to 4 sets of 6 to 10 reps, resting 60 to 90 seconds between sets. Pair it with an incline dumbbell curl that trains the stretched half of the range this exercise skips.
