The triceps muscle (and still the biceps muscle, to a certain extent).
During a cross body bicep curl exercise, the biceps brachii muscle is primarily worked.
Hamstring - Semimembraneous
When you preform an arm curl, you use your bicep muscle. it all depends on how you curl. If you curl straight up or do a twisting motion while curling. You use your shoulder and bicep and maybe a small portion of the pectoral muscle where it meets the shoulder.
The leg curl is a muscular resistance exercise that primarily works the quadriceps. It involves the knee joint and develops strength in the quadriceps at the front of the thigh.
During a cross body curl exercise, the biceps muscles are primarily worked.
The preacher curl exercise primarily targets the biceps muscle group.
A curl-up on a stable surface, rectus abdominis muscle activity was 21% of MVC and external oblique muscle activity was 5% of MVC.
The Agonist muscle. In contrast, the muscle group that has passive action(the muscle being stretched) is called the antagonis muscle. For example, when doing a bicep curl. Your biceps are the agonists and your triceps would be the antagonists.
During a cross body hammer curl exercise, the muscles primarily worked are the biceps brachii and the brachioradialis.
The Front Curl works with the biceps.

Is lowering the weight during a workout important? Eccentric contractions are the lowering ( lengthening technically) phase of an exercise. So lowering the weight after a bicep curl or bench press is the the eccentric phase. On a lat pulldown it’s actually when you are bringing the bar back up. The eccentric phase causes much of the muscle soreness we feel the next day but it also leads to small tears in the muscle cells which leads to one part of muscle growth. So they are beneficial parts of the exercise.
