Difficulty levels differ: EZ Bar Seated Close Grip Concentration Curl is intermediate, while EZ Barbell Close Grip Preacher Curl is beginner.
Both exercises target the Biceps using Ez-barbell. The main differences are in their movement patterns and muscle activation angles.

Pros & Cons

EZ Bar Seated Close Grip Concentration Curl

+ Pros

Strong peak contraction and unilateral focus to fix imbalances
Requires minimal specialized equipment
Easy to implement tempo and isometric holds for hypertrophy
Close grip increases short-head biceps emphasis and forearm involvement

− Cons

Requires strict bracing to avoid shoulder swing
Narrow grip can stress the wrist without correct alignment
Less consistent range of motion between reps if form drifts

EZ Barbell Close Grip Preacher Curl

+ Pros

Beginners friendly — pad enforces arm position and reduces cheating
Consistent ROM from stretched to contracted position
Better for progressive loading with heavier sets
Reduces trunk involvement, isolating the biceps effectively

− Cons

Needs a preacher bench or pad — less accessible at home
Start position puts biceps in a stretched, higher-tension spot that can irritate elbows for some lifters
Less peak contraction emphasis compared to unilateral concentration holds

When Each Exercise Wins

For muscle hypertrophy: Ez Bar Seated Close Grip Concentration Curl

Concentration curls let you maximize peak contraction and unilateral volume, which increases time under tension at short muscle lengths—ideal for 8–12 rep hypertrophy sets and targeted long-form isometrics.

For strength gains: Ez Barbell Close Grip Preacher Curl

Preacher curls allow heavier, more consistent loading through a full ROM with less cheating, making them better for progressive overload schemes and lower-rep strength work (4–6 reps).

For beginners: Ez Barbell Close Grip Preacher Curl

The preacher pad enforces fixed upper-arm position and reduces compensatory shoulder movement, so beginners learn strict elbow flexion mechanics faster and safer.

For home workouts: Ez Bar Seated Close Grip Concentration Curl

You only need an EZ-bar and a bench or chair to brace your arm; no specialized preacher bench is required, so it’s more practical for limited equipment setups.

Frequently Asked Questions

Can I do both Ez Bar Seated Close Grip Concentration Curl and Ez Barbell Close Grip Preacher Curl in the same workout?

Yes — pairing them works well: use the preacher curl earlier for heavier, compound-style sets (4–8 reps) and finish with unilateral concentration curls for 8–15 rep burnout sets or isometric holds to increase time under tension.

Which exercise is better for beginners?

The Ez Barbell Close Grip Preacher Curl is better for beginners because the pad locks the upper arm in place, enforces strict elbow flexion, and reduces compensatory movement, allowing safer load progression.

How do the muscle activation patterns differ?

Concentration curls bias peak contraction and short-range tension by isolating the distal biceps with unilateral bracing, while preacher curls create a stronger stretch at the start of the lift and emphasize constant tension through the ascending force curve and longer muscle lengths.

Can Ez Barbell Close Grip Preacher Curl replace Ez Bar Seated Close Grip Concentration Curl?

It can replace it if your goal is consistent loading and progressive strength; however, if you need to correct imbalances or emphasize peak contraction for hypertrophy, keep the concentration curl in your program as a complement.

Expert Verdict

Use the Ez Bar Seated Close Grip Concentration Curl when you want peak contraction, unilateral work to fix left-right differences, and hypertrophy-focused time under tension (8–15 reps, 2–4 second eccentrics, 1–2 second pauses at the top). Choose the Ez Barbell Close Grip Preacher Curl if you want a beginner-friendly, strictly loaded movement for progressive strength (4–6 or 6–10 reps) and consistent ROM. Both target the biceps strongly; pick the concentration curl for isolation detail and the preacher curl for scalable loading and technical consistency.
