Understanding the anatomy of biceps can help you get more out of your workouts, so let’s take a closer look at what muscles this exercise works.
This article will discuss the benefits of this classic arm exercise, its various variations, alternative exercises that target similar muscle groups as well as basic anatomy of the biceps muscle group.
So if you’re ready to learn about how to maximize your bicep workout, then read on!
Bicep Curls Muscles Worked
Bicep Curls: Muscles Worked
Primary Muscles Worked: The primary muscles worked when performing bicep curls are the biceps brachii. This muscle group is located on the front of your upper arm and consists of two heads, the short head and long head. Both heads originate from different points along your shoulder blade and insert at a common point near your elbow joint. When contracted, this muscle group flexes or bends your elbow joint, allowing you to curl a weight up towards your chest.
Secondary Muscles Worked: In addition to the biceps brachii, other secondary muscles also work during bicep curls. These include the brachialis which lies beneath the biceps brachii and helps with elbow flexion; as well as several smaller muscles in your forearm that help stabilize wrist movement while curling weights.
Finally, several stabilizing muscles throughout both arms are activated during a set of bicep curls in order to maintain proper form while lifting weights. These include small rotator cuff muscles such as the supraspinatus and infraspinatus which help keep shoulder blades retracted back; as well as larger back muscles like the latissimus dorsi which provide stability for torso movements while curling weights upwards towards chest level.
Bicep curls are an effective exercise for targeting the biceps, as well as secondary and stabilizing muscles.
Benefits of Bicep Curls
Not only do they help build strength, but they also provide several other benefits that can improve overall health and fitness.
Improved Strength and Muscle Tone
The primary benefit of bicep curls is improved strength and muscle tone in the upper arms. As you perform this exercise, your biceps contract to lift the weight up against gravity. This contraction helps to strengthen your arm muscles while also increasing their size as they become more defined with regular use. With consistent practice, you will be able to lift heavier weights over time as your muscles grow stronger.
Increased Mobility and Flexibility
In addition to increased strength, performing bicep curls regularly can also help increase mobility in your shoulders and elbows by improving joint flexibility. When done correctly, this exercise works all three heads of the biceps brachii muscle which helps promote full range of motion in these joints when lifting weights or performing everyday activities like carrying groceries or reaching overhead into cabinets or shelves.
Improved Posture and Balance
Finally, incorporating bicep curls into your workout routine can help improve posture by engaging core stabilizing muscles such as those found in the lower back region. These muscles support proper alignment throughout our body when standing upright or sitting down at a desk for long periods of time. Additionally, it strengthens smaller stabilizing muscles around our shoulder blades which are important for maintaining balance during activities like running or playing sports where quick movements may occur suddenly without warning requiring us to stay steady on our feet.
Bicep curls offer numerous benefits to those looking to increase their strength, muscle tone, mobility, flexibility, posture and balance.
Exercise Variations for Bicep Curls
The Standing Barbell Curl: This is a classic exercise for building strength and size in the biceps. It involves holding a barbell with an overhand grip, keeping your elbows close to your sides as you lift the weight up towards your chest. This exercise works both arms at once and can be done with heavier weights than other variations of curls. To make this exercise more challenging, try using a wider grip or adding pauses at different points during the movement.
Seated Dumbbell Curl: The seated dumbbell curl is another popular variation of bicep curls that targets the same muscles but allows for more control and isolation of each arm. This exercise requires sitting on a bench or chair while holding two dumbbells in each hand with palms facing up. Keeping your elbows tucked into your sides, slowly curl one arm up towards your shoulder before lowering it back down and repeating on the other side until all reps are completed. For added intensity, add pauses at different points throughout the movement or use heavier weights if possible.
Hammer Curl with a Resistance Band: To perform this exercise, stand with your feet hip-width apart and hold onto either end of the band. Keep your elbows close to your body and slowly curl your hands upwards until they reach shoulder height. Return them back down to the starting position and repeat until all reps are completed. To increase intensity, you can add pauses throughout this movement or use heavier bands if available.
Exercise variations for bicep curls can be used to target and strengthen the muscles in your arms, while also providing a great workout.
Alternative Exercises for Bicep Curls
Chin-ups and pull-ups are a great alternative to bicep curls. They target the same muscles in your arms, as well as your back and core.
To do chin-ups or pull-ups, grab a bar with an overhand grip that is slightly wider than shoulder width apart. Pull yourself up until your chin passes the bar then lower yourself down slowly until your arms are fully extended again. This exercise can be made easier by using assistance from a resistance band or spotter if needed.
Bent Over Rows with Dumbbells or Barbells: Bent over rows are another great alternative to bicep curls for targeting the same muscles in your arms and upper body.
To perform this exercise, stand with feet hip width apart while holding dumbbells or a barbell in each hand with palms facing inward towards you. Bend at the waist keeping your back flat so that it’s parallel to the floor and let the weights hang straight down from shoulders while maintaining control of them throughout movement. Then lift both weights up toward chest level while squeezing shoulder blades together before returning them to starting position under control again for one rep of bent over rows.
Cable rows: To perform these, sit on a bench facing away from the cable machine with your feet firmly planted on the ground and knees slightly bent for balance. Grab the handle attached to the cable machine with both hands about shoulder width apart then lean forward slightly at your hips while keeping your spine neutral throughout the entire motion.
Pull the handle towards your stomach area contracting your lats, rhomboids, traps, rear delts and other smaller stabilizing muscles along the way before releasing tension slowly after peak contraction has been reached completing one rep of this exercise.
These alternative exercises for bicep curls provide a great way to target the same muscles while also providing variety in your workouts.
Anatomy of the Biceps Muscle Group
The biceps muscle group is composed of two muscles: the biceps brachii and the brachialis. The primary function of these muscles is to flex the elbow joint, allowing for movement in activities such as lifting weights or carrying groceries.
Origin Points of the Biceps Muscle Group: The origin points for both muscles are located on either side of the shoulder blade, with one head originating from each scapula. Specifically, they originate from a small depression at the top portion of each scapula known as the supraglenoid tubercle.
Insertion Points of the Biceps Muscle Group: Both heads insert into a single tendon that crosses over to attach onto a small bump on your forearm called your radial tuberosity. This tendon gives rise to an easily visible bulge in your upper arm when you flex your bicep muscle group.
The biceps muscle group works together to produce elbow flexion and supination when contracted. This can be seen when performing exercises such as barbell curls or hammer curls with resistance bands.
Additionally, due to their attachment points on either side of the shoulder blade, they also help stabilize this area during overhead pressing motions like push-ups or military presses with dumbbells or barbells.
The anatomy of the biceps muscle group is essential to understand in order to properly perform exercises like bicep curls.
