Mainly back and bicep. Or specifically the sternal portion of the pectoralis major, latissimus dorsi, teres major, posterior deltoid, the rhomboids, the middle and lower portions of the trapezius, and the elbow flexors. It also depends on if you're doing chin ups, pull ups or lat pull ups.
Pull-ups primarily target the latissimus dorsi muscle group in the back, though many other muscles are involved in the movement. These assisting muscles include the brachialis, brachioradialis, biceps brachii, teres major, deltoid muscle, infraspinatus, teres minor, rhomboids, levator scapulae, trapezius lower, trapezius middle, and pectoralis minor. [3] The involvement of the biceps brachii however in the pull-up is much smaller than that of the chin-up, given the biomechanical disadvantage of the elbow when grasping the bar in a pronated position.
Since multiple joints are utilized, pull-ups are known as a compound exercise.
The bench press primarily targets the chest. It also targets shoulders, biceps and triceps
Latissimus dorsi, lower back muscles
Your lats! (in your back)
pectorials
The Front Curl works with the biceps.
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.
Primarily the lower chest muscles
The leg curl and leg extension exercises strengthens two muscle groups. The two muscle groups are the hamstring muscles and the quads or quadricep muscles.
The leg curl whether standing or sitting works the hamstring muscles, biceps femoris, which are on the back of the thigh.
True
Strength.
Very little. There is no resistance to exercise the muscle.
Hypertrophy.
Existing muscle cells increase in diameter.
Hypertension
The definition of muscular strength is the maximum amount of force that a muscle can exert against a form of resistance at one time. It is using muscles to exert force and refers to the amount of force those muscles produce.
