Preacher curls are one of the most effective exercises to get bigger, stronger and sculpted biceps. They set your arms on a tilting pad, discourage the cheating, raise the muscle tension and boost the bicep peak. In this article, the author discusses the objective of preacher curls, the differences between them in relation to normal curls, their advantages and disadvantages, as well as changes, prescribed weights, and why they are believed to be quite effective in arm building. It further touches on the mainstream strength benchmarks, such as curl benchmarks and bench press benchmarks, and how preacher curls help in supplementing the general growth of arms.
What Are Preacher Curls?
The preacher curls are isolation exercises of the biceps that are done on the preacher bench, which is a padded, angled surface that holds the upper arms. Preacher curls are supposed to make the biceps come into contraction and not move forward or backwards, as is in most cases during standing curls. Due to this rigidity, the preacher curls put continuous stress on the biceps brachii, brachialis, and brachioradialis.
The preacher curls can be used to achieve the best form, more time under tension and also to increase the size and thickness of the biceps. They may be performed with the help of different devices, including EZ-curl bar, dumbbells, barbells, or a cable system. The preacher arm position fixation makes preacher curls friendly to the beginner and challenging at the same time to the advanced lifter.
Arm position is among the largest contrasts between a regular bicep curl and a preacher curl. In a normal curl, the arms would be free, and the momentum or movement at the shoulders would help in the lift. In preacher curls, the arms remain straight, resulting in practically all the effort being handled by the biceps. This is the angle that makes it possible to get preacher curls to seem stronger with the lower weights.
Muscles Worked
- Biceps brachii (long head and short head) –major muscles of flexion of the elbow and of the bicep.
- Long head activation- increases the upper section of the bicep peak.
- Brachialis– a deeper muscle under the biceps that forces the biceps away, and therefore the arms appear fat.
- Brachioradialis – this is found in the forearm and provides strength in grip and growth of the arm.
Low and gradual movement during preacher curls makes sure that muscles remain in tension longer, which is optimal in terms of hypertrophy. Such tension initiates growth more than curl variations that are based on momentum.
Correct procedure of preacher Curls
The preacher curls need to be done well; you need to take a seat on the preacher bench and set the height of the bench such that the armpits come at the edge of the pad to be comfortable. Sit up erectly, with the chest directly up against the support. The feet are to be flat and steady.
Hold the bench with your palm upwards. You can hold a dumbbell in your hand and place both arms on the pad in case you have a dumbbell. Draw the weight in a slow circle with your hand upwards, with the most emphasis on your biceps at the top. As far as your utter control is possible, reduce the weight until your arms are fully extended.
Elbows must not fly off the pad, and the torso must be fixed. Breathing is also of concern: you breathe out as you are moving the curl up and in when it folds down. Preacher curls are also difficult to do, and when done correctly, it does not strain your joints too much.
Lifters have a question about whether it is good to have 20 kg in curls. A 20kg seated or standing curl is quite a respectable weight for a beginner. Even more impressive is a 20 kg preacher curl, since, with preacher curls, momentum is eliminated and form is rigidly defined. But it is good or not good depending on your level of experience, size of arms and training. The strict angle also makes preacher curls less weighty as compared to standing curls.
Benefits of Preacher Curls
Maximum Isolation
- The pad restricts shoulder and back involvement.
- Forces the biceps to contract more, which is essential for growth.
Constant Tension
- Maintains continuous stress on the muscle throughout the movement.
- Increases time under tension, a key principle of hypertrophy.
- Many athletes say it helps shape the lower part of the biceps and makes them appear more round.
Improved Mind–Muscle Connection
- Encourages better focus on the biceps during each rep.
- Leads to greater control and reduced injury risk.
Effectiveness for Bicep Development
- Yes, preacher curls do build the biceps.
- Work best when paired with compound pulling exercises like chin-ups and rows.
- Some lifters feel hammer curls or spider curls add more arm length, while preacher curls are among the best for building front-arm thickness.
Common Mistakes to Avoid
- One of the mistakes is the overload of weight. Preacher curls are done slowly and smoothly. Being overweight will lead to the rise or flaring of the elbows, which negates the aim of the exercise.
- Other errors are failure to extend completely at the bottom, excessive flexion of the wrists, backwards leaning and botching repetitions. These habits restrict development and slow down muscle movement.
- Other lifters even forget to warm up properly, thus increasing the possibility of straining the elbow. Preacher curls tend to strain the elbows, and this may be evident when done incorrectly. This is among the drawbacks of the preacher curls; they may cause discomfort when you have a problem with the elbow, or in case the pad height is wrong.
Variations of Preacher Curls
It is very diverse to make the preacher curls routine interesting. This is most commonly performed as the EZ-bar preacher curl so that basic strain on the wrist is minimised. This can be achieved through the use of the dumbbell preacher curl to regain the imbalance and create muscle symmetry. A barbell may also be loaded into preacher curls, and cable preacher curls also translate tension throughout the whole movement to the bottom.
Common Variations
- EZ-bar preacher curl – eliminates strain on the wrist.
- Dumbbell preacher curl- enhances symmetry and corrects asymmetry.
- Barbell preacher curl- can be loaded heavier.
- Cable preacher curl – It does not change its tension.
Spider curls are also done by other lifters, and they position the torso at the down position on an incline bench, forming a different angle of isolation. We can compare spider curls with preacher curls; as there is no universally bad or good one, since each of them has its benefits.
Additional Variations
- Spider curls- this focuses on the upper section of the biceps.
- Preacher curls- focus on full contraction.
The 7-7-7 approach, also called triple sevens, is another popular variation. It includes:
- 7 half-reps at the bottom
- 7 half-reps at the top
- 7 full reps
The method adds fatigue and attacks deep muscle fibres.
Provided that substitutes are necessary, incline curls or concentration curls can be used to provide the same isolation as preacher curls, but no bench is required. Other lifters even view them as being more versatile.
The sets must be 3 to 4 with 8-12 times in case of hypertrophy. Negatives are useful in the growth and enhancement of the duration of tension. When one wants to gain strength, heavy weights are recommended with 6-8 reps.
Recommended Sets and Reps
- Hypertrophy: 3–4 sets of 8–12 reps
- Strength: 6–8 heavy reps
- Side effects: time under tension.
The right weight will be a matter of individual preference. It is a good start of 512 kg to the hand (dumbbells) or 1525 kg with a barbell. A 20kg barbell can be light to one person and heavy to another person. Barbells have different weights, 20 kg, 25kg, and speciality rods may have 30kg and above. The majority of gyms carry a 6-foot rackable barbell.
The majority of people make comparisons of their curling strength with normal fitness indicators. The strength of 40 kg curls when done strictly is a strong one, yet only very experienced lifters achieve that level of strength. This is a 400 lbs bench press that is very rare and is commonly seen among hardcore athletes. Dwayne Johnson is said to be able to press 425-450lbs, and Arnold Schwarzenegger could press at least 500 lbs in his youth. The 170 lb man can lift 135-185lb on the bench, with a range of 135 to 185, based on the training rate.
Who Should Do Preacher Curls?
Preacher curls can be used to isolate the biceps. They are beneficial when training beginners in the right form, when the intermediate clear their body and gain development, and when the advanced athletes perfect the minor details of their work. Bodybuilders, fitness enthusiasts and even people in rehabilitation use them to fix bad curling habits.
The question that most people have is whether the biceps or one forearms is more important. Preacher curls mainly focus on the biceps, whereas both are significant. Hammer curls can also make the arms appear bigger by stimulating the brachialis; nevertheless, preacher ones work better when it comes to isolation.
Balanced training of the biceps requires one strict isolation exercise, such as preacher curls, and one heavy compound exercise, such as standing barbell curls.
The mention of great physiques will always cover names of Arnold Schwarzenegger, Ronnie Coleman, and more current celebrities such as Chris Bumstead. Muscular stars like Dwayne Johnson are prevailing in Hollywood to underline this image, and less-known actors are ironically referred to as unknown entertainers.
Final Thoughts
Preacher curls are still regarded as one of the most efficient and effective exercises to be performed to make biceps bigger, stronger and shapely. The strict form that they have enhances more control, further contraction, and continuity. Preacher curls are the supplement to any workout, regardless of whether you are trying to build bigger arms, gain more definition or improve to a better technique. When done correctly, using reasonable weight, intelligent programming, preacher curls can make you achieve the strong, carved arms you are targeting.
