How to perform Seated Close-Grip Concentration Barbell Curl
- Sit down on a flat bench with a barbell or E-Z Bar in front of you in between your legs. Your legs should be spread with the knees bent and the feet on the floor.
- Use your arms to pick the barbell up and place the back of your upper arms on top of your inner thighs (around three and a half inches away from the front of the knee). A supinated grip closer than shoulder width is needed to perform this exercise. Tip: Your arm should be extended at arms length and the barbell should be above the floor. This will be your starting position.
- While holding the upper arms stationary, curl the weights forward while contracting the biceps as you breathe out. Only the forearms should move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps.
- Slowly begin to bring the barbell back to starting position as your breathe in. Tip: Avoid swinging motions at any time.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Biceps (primary): bends the elbow and turns the palm up during pulls and curls.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the upper arm still and pinned to your side so the movement happens only at the elbow.
- Keep the bar path close and stacked over your mid-foot; letting it drift forward wastes force and loads the lower back.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Swinging the torso to fling the weight up instead of actually curling it.
- Loading the bar heavier than your form allows and turning strict reps into a whole-body heave.
- Chasing weight jumps before the current load feels solid on every rep.
