One of the reasons that pull-up is the best upper-body exercise is because it works out many upper body muscles at the same time. Here is a look at the muscles that pull-ups work and use:
This muscle is commonly referred to as ‘lats‘. It is a large and broad muscle in the back that is used in moving shoulders.
This muscle is commonly referred to as biceps. It is a flexor muscle that is located in front of the upper arm that flexes the forearm.
This muscle is commonly referred to as ‘traps‘. It is a large muscle that runs through the neck, shoulders and upper back.
This is a muscle of the upper forearm.
This is a thick triangular muscle that covers the shoulder joint.
This is a broad muscle that lies behind the Latissimus dorsi
Muscles in the upper back that help in the movement of the shoulder blade.
This is a large, long and flat muscle that runs along both sides of the abdomen.
These are muscles on either side of the torso.
A thick muscle located at the chest.
This is commonly referred to as triceps. It is a large muscle located on the back of the upper arm.
These pull-ups put more emphasis on the biceps.
A standard pull-up works out the back, biceps, shoulders and chest. But it does not stress as much on the lats as a wide-grip pull-up.
A wide-grip pull up differs from a standard pull-up in the grip that is used. In a wide-grip pull-up, the distance between both the hands is wider. This puts more emphasis on the lats.
