Does brachialis make the bicep wider?

Author: Manuel Wintheiser  |  Last update: Friday, November 28, 2025

The biceps muscle shares this function, but it also is responsible for the additional functions of supination of the forearm and flexion of the humerus at the shoulder. The brachialis is the muscle that is most responsible for bicep width and it's often sorely neglected in our training.

What increases bicep width?

The best exercise for growing the bicep muscle is any variation of the curl. Curls are best done using a barbell and weights or a set of dumbbells. If you're training in the gym, sitting at a bench or using the preacher curl machine can help to further concentrate tension on the bicep muscle, leading to bigger gains.

What does the brachialis do for the bicep?

The brachialis is an important flexor muscle of the forearm at the elbow. [1] The brachialis provides elbow flexion at all physiologic positions and is considered a "pure flexor" of the forearm at the elbow.

Will hammer curls make my biceps wider?

Comments Section If you mean the width from the front (the width of your arm you see if you're standing in front of the mirror), that gets wider with hammer curls. They target the brachialis muscle, which sits underneath the bicep and help push the biceps out when they get bigger, this making your arm wider.

Is bicep width genetic?

Earlier people assumed that they would get the results based on the extent of training. But over the years, scientists have proved that genetics is a determinant to why some people quickly build muscle and develop large biceps while others do not.

Is the brachialis stronger than the bicep?

The brachialis is the major flexor of the elbow. It has a large cross-sectional area, providing it with more strength than the biceps brachii and the coracobrachialis. In order to isolate the brachialis muscle the forearm needs to be in pronation, due to the biceps brachii's function as a supinator and flexor.

What is the brachialis responsible for?

The main function of the brachialis muscle is elbow flexion. It is one of the most important flexors of the elbow and allows for flexion of the elbow at various angles.

How important is it to train brachialis?

The biceps brachii and brachialis muscles are fundamental to forearm movement and elbow flexion, playing a significant role in both functional activities and athletic performance.

Are hammer curls better than bicep curls?

So, which is better? It really depends on your goals. If you're looking to build bigger biceps, then you should focus on bicep curls a bit more than hammer curls. However, if you're just looking to tone your arms and don't really care about building bigger biceps, then either exercise will work just fine.

What determines bicep size?

Many factors influence average bicep size. The main ones include body mass index, strength training, age, gender, and diet. Your BMI refers to the amount of body fat you have based on your weight and height. This impacts bicep size as a higher BMI contributes to a larger arm width, increasing bicep size.

How to grow a wider bicep?

How To Get Bigger Biceps: The 6 Best Exercises
  1. Concentration Curls (short head)
  2. Hammer Curls (long head)
  3. EZ Bar Curls (long / short head depending on grip)

Do pushups work the biceps?

Do Push Ups Work Biceps? Whilst the biceps help to stabilize the shoulder and elbow joints during the lowering phase of a push up, they don't directly work the biceps. If your goal is to build your biceps, you'd be better off focusing on bicep isolation exercises such as bicep curls, hammer curls, or chin ups.

Is a 2 finger bicep gap good?

For a quick test, bend your arm at the elbow joint in to a bicep curl. In this muscle contraction, as you're flexing the elbow, you can measure your bicep gap. If you can fit more than 2 fingers in the gap between your bicep and your elbow, you may have short biceps!
