Ez Bar Seated Close Grip Concentration Curl vs Ez Barbell Reverse Grip Preacher Curl: Complete Compa
Ez Bar Seated Close Grip Concentration Curl vs Ez Barbell Reverse Grip Preacher Curl — two isolation moves for your biceps that look similar but load the arm differently. You’ll get a breakdown of muscle activation, biomechanics, equipment needs, technique cues, rep ranges (6–12 for strength/hypertrophy, 12–20 for metabolic work), and programming tips so you can choose the right move for your goal. Read on to learn which exercise emphasizes the long head, which shifts load to the brachialis and forearms, and how to use them together in a weekly plan.

Key Differences
- 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 emphasis on biceps long head due to supination and elbow positioning
- Easy setup with just an EZ-bar and seat—high accessibility
- Excellent unilateral option to correct imbalances
- Low shoulder involvement, isolates elbow flexion effectively
− Cons
- Limited loading potential compared to compound moves
- Can encourage wrist ulnar deviation if grip is too tight
- Risk of cheating with torso sway if fatigued
EZ Barbell Reverse Grip Preacher Curl
+ Pros
- Greater brachioradialis and brachialis recruitment for thicker forearms
- Preacher pad locks elbow, reducing momentum and improving strictness
- Good for mid-range strength development and controlled negatives
- Clear progressive loading due to stable setup
− Cons
- Higher wrist and distal-biceps tendon stress with heavy pronation
- Requires a preacher pad or bench—less accessible at home
- Can underload biceps long head compared to supinated variations
When Each Exercise Wins
Its supinated grip and isolated elbow pivot increase biceps long-head tension and peak contraction; use 8–12 reps with 2–3s eccentrics to maximize time under tension.
The preacher pad enforces strict movement and mid-range loading, making it easier to add weight safely and build heavier, controlled reps in the 4–8 range.
Simpler setup and fixed elbow support make it easier to learn clean elbow flexion mechanics and avoid wrist/pronator strain during early training.
Needs only an EZ-bar and a bench or chair—no preacher bench required—so you can perform it effectively in most home setups.
Frequently Asked Questions
Can I do both Ez Bar Seated Close Grip Concentration Curl and Ez Barbell Reverse Grip Preacher Curl in the same workout?
Yes. Use one as your primary heavy set (e.g., 3–4 sets of 6–8 on the preacher for strength) and the other as a higher-volume finisher (e.g., 2–3 sets of 10–15 concentration curls). Sequence strict to fatigue-safe: stronger, stabilized work first, isolation finish last.
Which exercise is better for beginners?
The seated close-grip concentration curl is better for beginners because it stabilizes the elbow, reduces compensatory movement, and teaches clean supinated elbow flexion with low equipment needs.
How do the muscle activation patterns differ?
Concentration curls bias the biceps long head via supination and favorable moment arms, creating a higher peak at terminal flexion. Reverse-grip preacher curls reduce biceps supination contribution and shift activation toward the brachialis and brachioradialis, producing a flatter mid-range load profile.
Can Ez Barbell Reverse Grip Preacher Curl replace Ez Bar Seated Close Grip Concentration Curl?
It can replace it when your goal is forearm and brachialis development or strict mid-range strength, but it won’t fully match the biceps long-head emphasis and peak contraction you get from the supinated concentration curl.
Expert Verdict
Use the Ez Bar Seated Close Grip Concentration Curl when your goal is targeted biceps long-head hypertrophy, unilateral correction, and minimal equipment setup. Keep reps mainly in the 8–12 range and emphasize a 2–3 second eccentric and full supination at the top. Choose the Ez Barbell Reverse Grip Preacher Curl when you want strict mid-range strength, greater brachialis/brachioradialis development, and progressive loading with less shoulder involvement; keep reps in the 4–8 or 8–12 ranges depending on strength vs hypertrophy focus. Pair them across cycles—use concentration curls during hypertrophy phases and reverse preacher curls for strength blocks or forearm emphasis.
