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 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 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.

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.
The muscular system is torn slightly with strenuous exercise, especially with weight lifting. Once a muscle is torn through exercise, it recovers, and makes this muscle bigger, stronger and tougher. Therefore, all muscles are similar to callouses.
