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.
During a cross body curl exercise, the biceps muscles are primarily worked.
If you are referring to the dumbbell bench press, which works both arms independently, then the muscles being worked are mainly the pectoral and tricep muscles. Other muscles that are indirectly involved are the shoulder (deltoids and trapezius) and the lats (latissimus dorsi).
During a cross body hammer curl exercise, the muscles primarily worked are the biceps brachii and the brachioradialis.
During a cross body bicep curl exercise, the biceps brachii muscle is primarily worked.
During a single arm press exercise, the muscles primarily worked are the deltoids (shoulders), triceps (back of the arms), and chest muscles.
Hamstring - Semimembraneous
The triceps muscle (and still the biceps muscle, to a certain extent).
During a single arm shoulder press exercise, the deltoid muscles in the shoulder are primarily worked. Additionally, the triceps and upper back muscles are also engaged to stabilize and support the movement.
The most common exercises for strengthening your arm muscles include: Biceps: Seated curls Standing curls Triceps: Tricep extensions Lat pulldowns Pull Ups Dips Forearms: Reverse curl Wrist curl Rock climbing
The main muscle used in curls is the biceps.
The muscles worked during a front lever exercise include the core muscles, back muscles, shoulder muscles, and arm muscles. These muscles are engaged to maintain the body in a horizontal position while hanging from a bar or rings.
The single arm overhead press exercise primarily works the deltoid muscles in the shoulders, as well as the triceps in the arms and the core muscles for stability.
