Two uses are: to practice arm strength, and to practice hand grip strength.

Benefits: The benefits of using a pull-up machine lie in the fact that the biceps brachii is a muscle with two heads, and its primary function is to bend the arm. During the bending action, another muscle, the brachialis, is also involved. However, it is only when performing movements that involve raising the forearm, such as high-position pull-up or reverse high-position pull-up, that the brachialis can be fully exercised. Additionally, the main muscle in the upper forearm, the brachioradialis, plays a significant role in the bending action. By performing side pull-ups with a pull-up machine, the brachialis can be strengthened.

Here are some exercise methods:
Action:

High-Position Dumbbell Curls with Both Hands

Standing Dumbbell Curls with Both Hands

Standing single-arm pull-down machine bicep curl
Single-handed exercises can make the effect more concentrated, and at the same time, they also give you the opportunity to use the flip palm action (palm inwards to palm upwards), to fully stimulate the biceps.

Action: Try to keep your upper arm stationary, bend the elbow joint, and pull the handle towards the shoulder through the chest with the power of your biceps. When you reach the maximum contraction position of the muscle, the elbow should be pointing directly at the low-position pulley. Then return to the starting position. Alternate arms.。
