The leg press works mostly the quadriceps muscle group. The top half, front of your legs above the knee to your hip. If you finish the leg press with a toe raise at the and of each press you will also benefit greatly with strengthened feet, ankles, and calf muscles. Always remember to stretch and be able to press at least 20 times without stopping before moving to a higher weight. This helps strengthen the body, muscles, connective tissues like the tendons etc. to help prevent undue injury from, increasing the weight strain on your body parts before they have a chance to properly adjust to the new weight load.
hamstring
no but it does build muscle
The leg extension exercise primarily targets the quadriceps muscle group in the front of the thigh.
Leg raises primarily target the lower abdominal muscles, while sit-ups engage both the upper and lower abdominal muscles. Sit-ups are generally more effective for overall abdominal muscle strengthening, while leg raises are more focused on the lower abs.
Crunches primarily target the upper abdominal muscles, while leg raises target the lower abdominal muscles. Both exercises are effective for abdominal muscle development, but leg raises may engage the lower abs more intensely. Varying your routine with both exercises can help achieve overall abdominal strength and definition.
the quadriceps
There are a variety of exercises someone could do to help strengthen their calf muscle. Single-leg and double-leg calf raises are a great exercise for your calves as well as stretching and running.
Flexing the thigh, extending the leg, adducts leg
the prosterby muscle is the answer
the prosterby muscle is the answer
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.
Using a seated leg raises machine can help strengthen the lower body muscles, including the quadriceps, hamstrings, and glutes. This exercise can improve muscle tone, increase muscle strength, and enhance overall lower body stability and balance.
