The ultimate guide to bicep curls to help sculpt stronger arms

Bicep curls are fundamental strength-training exercises that target the biceps brachii muscles in the front of the upper arms.

They are isolation exercises that involve lifting weights in a controlled manner to improve arm strength and muscle definition.

You can perform bicep curls using various equipment such as dumbbells, barbells, or resistance bands, making them a versatile choice for upper-body workouts.

Bicep curls are a staple in strength training environments for enhancing functional and aesthetic aspects of arm strength.

Target muscles: Biceps
Required equipment: Dumbbells, barbells with weight plates, resistance bands, or cable machine

How to do bicep curls with proper form

Below are the steps to follow to perform bicep curls with proper form.

• Select dumbbells of appropriate weight.
• Stand upright with a dumbbell in each hand, arms fully extended, and palms facing forward.
• Keep your feet at shoulder-width.
• Grasp the dumbbells with a neutral grip with palms facing forward. Allow your wrists to remain in a comfortable and natural position.
• Engage your core and keep your back straight.
• Keep your elbows close to your torso.
• Exhale, bend your elbows and start curling the dumbbells. Keep your upper arms stationary and only move your forearms.
• Continue curling while contracting your biceps until the dumbbells are close to your shoulders.
• Stop curling when your forearms are nearly perpendicular to the floor.
• Hold this position for a brief moment to fully engage your biceps.
• Inhale and slowly lower the dumbbells back to your starting position, maintaining control throughout the descent. Do not allow the weights to drop quickly, as that can strain your muscles and joints.
• Repeat 8-12 reps per set and 3-4 sets in a session.

Tips

• Ensure you achieve a full range of motion by fully extending your arms at the bottom of each repetition and contracting your biceps at the top.
• Do not use momentum to swing the weights up. That can reduce the effectiveness of the exercise and increase the risk of injury.
• Prioritize control and proper form over lifting heavy weights.
• Using a weight that allows you to maintain good form is more beneficial than one that forces you to compromise your technique.
• Aim for 3-4 sets of 8-12 repetitions per set in a session. This rep range is best for building muscle and strength.
• Allow sufficient rest between sets to recover, usually around 60-90 seconds.

Tips and best practices for bicep curls

Below are some tips and best practices to enhance your bicep curl technique and maximize results.

• Warm-up
  Always warm up your muscles before starting your bicep curls.
  Light cardiovascular activity and dynamic stretching can help increase blood flow and prepare your muscles for exercise.
• Start light
  Start with a lighter weight to ensure proper form and avoid straining your muscles.
• Proper grip
  Maintain a neutral grip on the dumbbells or barbell.
  That can reduce strain on your wrists and allow you to go through the curling motion better.
• Engage your core and stabilizer muscles
  Tighten your core muscles and maintain good posture throughout the exercise.
  That can help stabilize your body and prevent excessive swaying or using momentum to lift the weights.
• Elbow position
  Keep your elbows close to your torso and stationary.
  That can isolate the biceps and prevent swinging, ensuring that the biceps do most of the work.
• Full range of motion
  Perform a full range of motion on each repetition. Fully extend your arms at the bottom and fully contract your biceps at the top of the curl.
• Avoid jerking
  Lift the weights in a controlled manner. Avoid sudden jerking or swinging. Jerking can lead to injuries and reduce the effectiveness of the exercise.
• Breathing
  Exhale as you curl the weights upward, and inhale as you lower them.
  That helps to stabilize your core and provide oxygen to your muscles.
• Concentration
  Focus on the contraction of your biceps throughout the movement.
  Visualizing the muscle working can help establish a strong mind-muscle connection.
• Variation
  Incorporate bicep curl variations into your training regimen.
  That can help target different parts of the biceps and forearms.
• Progressive overload
  Gradually increase the weight you’re lifting as your strength improves. However, prioritize proper form over heavy weights.
• Rest and recovery
  Allow adequate rest between sets and workouts to promote muscle recovery and growth.
• Consistency
  Bicep curls, like any exercise, require consistency for noticeable results. Include them regularly in your strength training regimen.
• Cross-training
  Remember that bicep curls are just one part of a balanced workout regimen.
  Thus, incorporate other compound movements and exercises into your training to help work multiple muscles.
• Hydration and nutrition
  Stay hydrated and fuel your body with proper nutrition to support muscle growth and recovery.
• Consult a professional
  Newbies and exercisers with pre-existing conditions should consider consulting a fitness professional to ensure they perform bicep curls correctly and safely.

Bicep Curls – Common Mistakes

• Using momentum
  Swinging your body to lift the weights takes the focus away from the biceps and reduces the effectiveness of the exercise.
  Keep your upper body stable and use controlled movements.
• Incomplete range of motion
  Not fully extending your arms at the bottom or fully contracting your biceps at the top of the movement can limit muscle activation.
  Aim for a full range of motion in each repetition.
• Lifting too heavy
  Too heavy weights can compromise your form and increase the risk of injury.
  Start with a weight that allows you to maintain proper technique throughout the set.
• Shoulder involvement
  Allowing your shoulders to shrug or elevate during the curl shifts the emphasis away from the biceps.
  Keep your shoulders relaxed and focus on isolating the biceps.
• Curling wrists
  Curling your wrists inward during the movement can strain your wrists and reduce the effectiveness of the exercise.
  Maintain a neutral wrist position.
• Leaning back
  Excessively leaning backward or arching your back can strain your lower back and compromise your posture.
  Stand upright and engage your core muscles.
• Neglecting the eccentric phase
  The lowering or eccentric phase of the curl is just as important as the lifting phase.
  Control the weights on the way down. Do not let them drop quickly.
• Neglecting bracing
  Failing to engage your core and stabilizing muscles can lead to poor form.
  Brace your core muscles to maintain stability and prevent excessive swaying.
• Incorrect breathing
  Improper breathing can impact your stability and muscle engagement.
  Exhale as you lift the weights and inhale as you lower them.
• Overtraining
  Bicep curls are effective, but overtraining them without allowing adequate recovery can lead to injury.
  Incorporate variety and give your muscles time to rest.
• Poor choice of equipment
  Using equipment that doesn’t fit your hand size or grip can affect your form.
  Choose dumbbells or a barbell that you can give a comfortable grip.
• Not adjusting for body mechanics
  People have different body proportions, which can impact the ideal curling path.
  Adjust your hand position and movement path to suit your mechanics.
• Ignoring form for repetitions
  Prioritize maintaining proper form over the number of repetitions or weight lifted.
  Quality reps are more valuable than quantity.
• Rushing
  Performing bicep curls too quickly can compromise form and reduce muscle engagement.
  Focus on controlled, deliberate movements.
• Skipping warm-ups
  Failing to warm up properly can increase the risk of injury.
  Perform dynamic stretches and light cardio before starting your bicep curls.

  The strength gained from bicep curls might not necessarily translate directly to real-world functional tasks that involve multiple muscle groups and complex movements.

Bicep curls – variations to consider

Incorporating the following bicep curl variations into your workout can help spice up your training, keep them interesting, and help keep you motivated to push you toward your goals.

Resistance Band Bicep Curls

The resistance band bicep curls is a bicep exercise performed using resistance bands.

This exercise is an excellent variation for bicep curls for those seeking an effective alternative to traditional dumbbell or barbell curls.

The resistance band bicep curl primarily targets the biceps brachii muscle while engaging other supporting muscles.

Steps to follow

• Anchor the resistance band securely, such as under your feet or around a stationary object at a height that allows proper resistance.
• Stand up straight, holding the resistance band handles in each hand, arms fully extended, and palms facing forward. Keep your feet at shoulder-width.
• Exhale and curl your hands toward your shoulders, contracting your biceps against the band’s resistance.
• Hold the contracted position briefly at the top as you squeeze your biceps.
• Inhale and slowly lower your hands to your starting position, maintaining control against the band’s resistance throughout the descent.
• Repeat 8-12 reps for a set and 3-5 sets to complete a session with 60-90 seconds rest between sets

Fat Grip Bicep Curls

Fat grip bicep curls involve using a specialized attachment called a “fat grip” or “thick bar” during the curling movement.

The attachment increases the diameter of the barbell or dumbbell, making the grip thicker than a standard bar.

The exercise targets the biceps brachii muscle but also offers additional benefits due to the increased grip thickness.

Steps to follow

• Attach the fat grip to a barbell or use dumbbells designed with built-in thicker handles.
• Stand up straight with the barbell or dumbbells in your hands, arms fully extended, and palms facing forward.
• Keep your feet at shoulder-width.
• Exhale and curl the barbell or dumbbells while contracting your biceps.
• Continue raising the weight until your biceps fully contract and the barbell or dumbbells are at shoulder level.
• Hold the contracted position for a brief pause as you squeeze your biceps.
• Inhale and slowly lower the barbell or dumbbells back to the starting position.
• Repeat 8-12 reps for a set and 3-5 sets to complete a session with 60-90 seconds rest between sets.

TRX Bicep Curls

TRX bicep curls are a variation of the traditional bicep curls that utilize TRX suspension straps to create resistance and instability.

The exercise targets the biceps brachii muscle but adds an element of instability, which engages additional stabilizer muscles.

Steps to follow

• Adjust the TRX straps to an appropriate length. Ensure you fully extend your with the handles at chest height.
• Stand facing the anchor point of the TRX, holding the handles with an underhand grip with your palms facing upward.
• Walk backward to create tension in the straps, and take a step back so you are leaning away from the anchor point.
• Keep your elbows close to your torso and your upper arms perpendicular to the floor.
• Exhale and curl your hands toward your shoulders while contracting your biceps.
• Keep your body stable and maintain tension in the TRX straps.
• Pause briefly at the top of the contracted position and squeeze your biceps.
• Inhale and slowly lower your hands to your starting position, maintaining control and tension in the straps throughout the descent.
• Repeat 8-12 reps for a set and 3-5 sets to complete a session with 60-90 seconds rest between sets for muscle hypertrophy.

Cross Body Hammer Curls

Cross-body hammer curls are similar to regular hammer curls, but with a twist: you curl the weight across your body from one side to the opposite shoulder.

Steps to follow

• Stand upright with a dumbbell in each hand, arms fully extended, and palms facing your torso.
• Keep your feet at shoulder-width.
• Exhale and curl one dumbbell while contracting your biceps without moving your upper arms.
• Continue raising the weight diagonally across your body, and bring it up toward your opposite shoulder.
• Pause briefly at the top, hold the contracted position, and squeeze your biceps.
• Inhale and slowly lower the dumbbell to your starting position.
• Repeat the same steps with the other arm.
• Alternate between arms.
• Aim for 8-12 reps per side in a set and 3-5 sets overall to complete a session. Rest for 60-90 seconds between sets for muscle hypertrophy.

Reverse Grip Curls

The reverse grip curls use an underhand grip with palms facing upward instead of the standard overhand grip.

This variation changes the focus and engages the biceps and other muscles. It is an excellent exercise for targeting the brachialis, brachioradialis, and forearm.

Steps to follow

• Stand up straight with a barbell, hands grasping the bar with an underhand grip, with your palms facing upward.
• Keep your arms slightly wider than shoulder-width apart.
• Keep your upper arms close to your torso, and without moving your upper arms, exhale and curl the barbell while contracting your biceps.
• Continue raising the weight until you fully contract your biceps and the barbell is at shoulder level.
• Hold the contracted position for a brief pause and squeeze your biceps.
• Inhale and slowly lower the barbell back to the starting position.
• Repeat 8-12 reps for a set and 3-5 sets to complete a session with 60-90 seconds rest between sets for muscle hypertrophy.

Single-Arm Curls

Single-arm curls are a variation of the traditional bicep curl exercise performed with one arm at a time. It involves lifting a weight using only one arm while the other remains stationary.

The variation allows you to focus more intensely on each bicep individually.

It can help address muscle imbalances between your left and right arms. It ensures each side works independently and can help you develop balanced bicep strength.

Iso Hold Curls

Iso hold curls, also known as isometric hold curls, are a unique variation of the traditional bicep curl exercise.

It involves performing a bicep curl motion with weights as usual. But, you pause and hold the contraction at a specific point instead of completing the full range of motion.

The goal is to maintain an isometric contraction, where you engage the muscles without any change in length.

For example, during an iso hold curl, you might curl the dumbbell or barbell up to a 90-degree angle at the elbow and hold that position for a duration. That challenges the biceps to work against the resistance in a static state, effectively engaging the muscle fibers.

Eccentric Curls

Eccentric curls, also known as negative curls, are a type of bicep curl variation that focuses on the eccentric or lowering phase of the exercise.

Eccentric Curls emphasize lowering the weight to its starting position under control. That phase of the movement places more stress on the muscles, contributing to muscle growth and strength development during the repair process.

Steps to follow

• Start by lifting the weights with both arms using a traditional curling motion.
• Lower the weights back down to your starting position slowly and with control. Ensure this phase takes longer than the lifting portion.
• Focus on feeling the muscle engagement as you lower the weights, and avoid letting them drop quickly.

Eccentric Curls can lead to higher muscle soreness. Thus, start with a lighter weight than you would use for traditional curls. You might also want to incorporate them periodically into your training rather than during every workout.
