If you are building out biceps training, the Preacher Curl Ez Bar Close Grip is a intermediate-level option that uses ez bar. Mechanically, the target muscles bend the elbow and supinate the forearm — the reason this exercise carries over to pulling strength and elbow control. What separates this variation from other biceps work is that it is using a narrow hand spacing — a detail that changes which fibres take the load and how much stability the movement demands. Note the 'Preacher Curl Bar Close' component of the name: it specifies how this variation differs from otherwise similar biceps movements. Support comes from the forearms and brachialis; the forearms in particular help control the wrist and maintain grip, which is why fatigue there often shows up before the biceps is fully worked. Training this with ez bar angles the wrists into a more comfortable position than a straight bar, though it slightly reduces the supination demand on the biceps. Programme it alongside your other biceps work rather than as a standalone. It assumes you already own the basic pattern and can maintain position under moderate load.
The Preacher Curl Ez Bar Close Grip is primarily a biceps exercise, but it is never only the biceps doing the work.
The general rule for the Preacher Curl Ez Bar Close Grip is simple: inhale on the lowering phase, exhale as you pull. For heavier sets, take a breath in at the start position, brace as though bracing for a punch, and hold that pressure through the hardest part of the rep before exhaling. Getting this right stabilises your trunk and keeps blood pressure in a sensible range.
Shorten the range of motion to the portion you can control, then extend it as confidence builds. If ez bar feels unmanageable, rehearse the same pattern with bodyweight first. Stay at this level until every Preacher Curl Ez Bar Close Grip rep looks the same as the first.
Increase total working sets before increasing load — volume drives most of the adaptation at this stage. Track your Preacher Curl Ez Bar Close Grip numbers so you can see whether the biceps is actually progressing.
Add a drop set on the last working set to extend the stimulus beyond your normal stopping point. Use the Preacher Curl Ez Bar Close Grip as your accessory once your main biceps lift is done for the day.
The Preacher Curl Ez Bar Close Grip suits most healthy trainees, but it is not appropriate for everyone.
This is general educational information, not medical advice. If you are managing an injury or medical condition, check with a qualified professional before adding this exercise to your programme.
It primarily trains the biceps, with the forearms and brachialis assisting. The pattern is classified as pull, so the lats, mid-back, rear delts and biceps share the workload.
It is rated intermediate. You should already be comfortable with basic biceps work and able to hold position under moderate load before attempting it.
A practical starting point is 4 sets of 4-6, resting 3 min between sets, roughly 2-3x per week. Adjust from there based on how you recover.
You need ez bar. This angles the wrists into a more comfortable position than a straight bar, though it slightly reduces the supination demand on the biceps.
As a general rule, inhale on the lowering phase, exhale as you pull. Avoid holding your breath for the entire set.
Using momentum from the lower back to swing the weight. The simplest correction is to lead with the elbow rather than the hand so the back does the work instead of the arms.
Good substitutes that train the same biceps pattern include Biceps Curl Cable Wide Grip, Barbell Lap Curl, and Hammer Curl Resistance Band Simultaneous. Pick whichever matches the equipment you have available.
Add a small amount of load once you can complete every set at the top of the rep range with clean technique. Keep tempo and range consistent so the comparison is honest.
The Preacher Curl Ez Bar Close Grip fits into that picture as an intermediate option using ez bar, leaning on the forearms and brachialis alongside the biceps.
The biceps brachii is the muscle most people picture when they think of arm training. It sits on the front of the upper arm and has two heads — a long head on the outer arm and a short head on the inner arm — that together flex the elbow and rotate the forearm so the palm faces up (supination). Working alongside it are the brachialis, which lies underneath and pushes the biceps up to add peak and width, and the brachioradialis of the upper forearm.
Although the biceps is a small muscle, it responds extremely well to direct training and a higher frequency than most lifters use. The classic curl is the cornerstone, but the angle and grip you choose change which part of the muscle is emphasised. Standing barbell and dumbbell curls build overall mass. Incline curls put the long head on stretch and develop the outer biceps. Preacher curls isolate the short head and remove momentum. Hammer curls, performed with a neutral grip, target the brachialis and brachioradialis to thicken the whole arm.
For growth, the biceps thrive on moderate to high rep ranges, typically 8 to 15, with a focus on full range of motion and a hard squeeze at the top. Because the muscle is small and recovers quickly, training it two or even three times per week — including the work it already gets from back exercises — is both safe and productive for most people.
The most common mistake in biceps training is using too much weight and swinging the torso to heave the dumbbells up. This shifts the load onto the front delts and lower back and robs the biceps of tension. Instead, keep the elbows pinned to your sides, control the lowering phase for a full second or two, and resist the urge to let the weight drop. Avoid fully relaxing at the bottom of each rep; keeping constant tension produces a much stronger growth stimulus than ego-driven heavy partials.
Strong biceps are not just about appearance — they contribute to grip strength, pulling power, and elbow health. Pairing direct curl work with the heavy pulling you already do for back creates the best of both worlds. Use the popular biceps exercises below to build a focused arm routine.
